3D Full Color Effect 3000MW RGB Laser Scanner Lights DJ Party Bar Projector Stage Lighting

RGB laser stage lighting

You will find some examples of professional low-energy RGB weak laser projectors in our new cutting-edge F2700 FB4 diode laser show structures. All these RGB laser light projectors can satisfy even the most worried customers, and can deliver satisfactory and reliable overall laser performance to your venues, events and even Christmas lighting.

The more effective RGB light laser is suitable for large indoor venues and possibly smaller outdoor competitions. It is mainly a complete projector based on Atom 12 and Atom 15 laser diodes. For large-scale outdoor activities, we recognize our NF and F2 varieties, which can effectively and surprisingly see the laser at a long projection distance, and can be used by many professional products all over the world.

RGB laser stage light explanation

The so-called "RGB laser light projector"-in the amusement industry, it is a tool that can simultaneously emit purple, inexperienced and blue laser beams in the unmarried beam, and modulate each salvation on the same thyme Depth => So it has the ability to output hundreds of secondary mixed colors, covering the largest part of the mild spectrum seen. If the soft RGB laser colors are mixed in an appropriate ratio, the resulting laser beam is white.

RGB gentle stage laser lights are also commonly referred to as complete redemption laser projection equipment or white gentle lasers.

RGB laser light stage lighting: Newfeel F4700 FB4 & Spectrum 20 (large one)

The high satisfaction and accuracy of the secondary mixed laser color including white is achieved by using many elements, the most important of which is the temperature balance of the equipment; the size, form and size of the weak beam of purple, inexperienced and blue lasers Divergence; and the overall modulation performance of each laser module inside the laser device. It is also important to apply a satisfactory laser manipulation device (for example via ILDA, DMX or ArtNET) and effectively install all parameters in the laser manipulation software program so that your complete life-saving laser operates in its best condition.

As with any laser show equipment (we do not recommend using laser pointers), there are many reasonably priced RGB lasers on the market, few are worthy of respect, and some are incredibly (and unnecessarily) expensive. Nowadays, most of the lasers in low- and medium-energy lasers are re-evaluated as semiconductor laser diodes. There are dozens of different laser diodes on the market that can be used to produce laser modules. The cost of RGB laser light projectors will continue to somehow deny the high satisfaction (but should not be astronomical) of the laser diodes and beam shaping optical additives used in that particular RGB light laser projector.

The commonly used semiconductor laser diodes in the production of RGB laser light projectors have a wavelength of 635-660nm purple rescue, 520nm inexperienced rescue, and 445-460nm blue rescue laser. The output energy of this laser module can be 10W, 20W, 30W, or any wattage you like, currently as high as 100W.

637nm diode laser softening module-for high-energy RGB laser soft projector

Most customers will move after using the complete Salvation Laser Show equipment instead of the Unmarried Salvation Laser. RGB laser light projectors are more flexible than unmarried redemption light projectors, and they may be suitable for approximately 95% of all laser show applications.

RGB laser light projectors use Newfeel to synthesize various output powers, from low-energy lasers for underground golf equipment and small celebration venues to effective laser performance structures for large-scale events, festivals, and hiking, and long-distance outdoor advertising.

SPECTRUM 30W IP54 mixes uncooked coherent energy with the cutting-edge of natural diode technology, and promotes this through special optical technology, thus creating a lovely excess energy laser projection device. Ideal for large indoor venues and stadiums, large outdoor performances, festivals, travel and permanent installations

The lamp is guaranteed to output 29,000-30,000mw; it combines Newfeel's natural diode purple and blue modules, and an inexperienced COHERENT OPSL module. This total produces a lovely white balance (red: 8W/637nm + green: 10W/532nm OPSL + blue: 11W/445+460nm). In addition, the natural diode modules used are covered with the help of LASORB to obtain brighter additional colors and longer service life. It is also equipped with a Cambridge 6215 optical scanning device, which can achieve a very fast experiment speed of 30K @ 8° optics. The X axis and Y axis each have a maximum experimental viewing angle of 80°, which can produce lovely text backgrounds.

nt, pictures and logos, and large viewing angle beam results.

The device also has built-in Pangolin FB4-MAX, which can be fully operated by community connection (cat5/cat6) or using ArtNet and DMX.

The laser light also includes a free sturdy plastic flight case, ILDA cable, emergency stop system, interlock, key switch and mechanical shutter. It fully complies with all US CDRH/FDA regulations, as well as European and different global regulations. SPECTRUM 30 OPSL has become advanced and can provide customers with preferential prices for laser projection equipment, and at the same time put forward the high satisfaction requirements of Newfeel experts that you can trust. These structures are completely synthesized in Europe, using the simplest and best additives and construction techniques. You can click here to learn how these lasers are manufactured in Newfeel's factory.

The Newfeel natural diode module and OPSL module used inside the SPECTRUM 30 OPSL are custom manufactured and inspected at the Newfeel factory. They have a super beam divergence angle (<1mrad) and beam diameter (6x5.5mm), while producing a pleasant white balance. Through the complete analog modulation, you can generate thousands of different color combinations, as well as easy mobile fades and transitions. With the help of LASORB, the laser diode used inside the Newfeel module is covered, so you can further understand that your laser will no longer be damaged by ESD or energy surges.

This SPECTRUM 30 OPSL device is also equipped with Cambridge 6215 optical scanning device, which can generate lovely text content images and logos, as well as large viewing angle beam results (30K @ 8° optics, each experimental viewing angle is 80° X-axis and Y-axis) . With SPECTRUM 30 OPSL, you can recognize that your device can manage any content material or display you want to play.

These structures can be managed through ILDA, SD card, DMX or ArtNet without any problems. Moreover, they are also compatible with DiscoScan 2.zero and security scanning lenses, with a commercially available optical improvement structure, which is very suitable for places where you want unmarried lasers to cover huge projection places, or where you want to give the target place market scan results security.

The external operation below the laser light can also change the color, size, position, rotation, etc., which is very clean. In addition, these structures will integrate the PASS of pangolins to scan for compliance in the target market in the United States. They also own Pangolin's FB4 hardware, which is used by the entire community to operate your laser display.

3D laser scanner on Android phone / Habr

I present to your attention a DIY scanner based on an Android smartphone.

When designing and creating a scanner, first of all, we were interested in scanning large objects. At least - a full-length figure of a person with an accuracy of at least 1-2 mm.

These criteria have been successfully met. Objects are successfully scanned in natural light (without direct sunlight). The scanning field is determined by the capture angle of the smartphone camera and the distance at which the laser beam remains bright enough for detection (during the day indoors). This is a full-length human figure (1.8 meters) with a grip width of 1.2 meters.

The scanner was made for reasons of "whether to do something more or less useful and interesting when there is nothing to do." All illustrations are based on the example of a “test” object (it is not correct to post scans of people).

As experience has shown, for a scanner of this type, software is secondary and the least time was spent on it (on the final version. Not counting experiments and dead ends). Therefore, in the article I will not touch on the features of the software (Link to source codes at the end of the article.)

The purpose of the article is to talk about the dead ends and issues collected on the way to creating the final working version.

For the scanner in the final version is used:

Samsung S5 phone
30mW red and green lasers with line lens (90 degree line) with glass optics (not the cheapest).
Stepper motors 35BYGHM302-06LA 0.3A, 0.9°
Stepper motor drivers A4988
Bluetooth module HC-05
STM32F103C8t board

The A4988 drivers are set to half step, which with a 15->120 reducer gives 400*2*8 steps per PI.

Select the scanning technology.

The following different options were considered.

LED Projector.

The option was considered and calculated. Even expensive projectors do not have the required resolution to achieve the required accuracy. And it makes no sense to even talk about cheap ones.

Mechanical sweep of the laser beam in combination with a diffraction grating.

The idea was tested and found to be suitable. But not for DIY performance, for reasons:

A sufficiently powerful laser is needed so that after diffraction the marks are bright enough (the distance to the smartphone lens is 1..2 meters). And the eyes are pitiful. A laser point already with 30mW is not useful.
Mechanical reamer accuracy requirement in 2 planes is too high for DIY implementation.

Standard mechanical scanning of the laser line on a stationary scanned object.

In the end, a variant with two lasers of different colors was chosen

Different colors of lasers make it possible to independently detect them in one frame.
The location of the lasers on different sides of the camera allows you to get two scans in one pass.
Two scans at a time allows you to objectively evaluate the quality of the scanner alignment (the scans should converge and overlap each other).

As it turned out, the last criterion is the most important. The quality of the scan is entirely determined by the accuracy of measuring the geometric dimensions and angles of the scanner. And the presence of two scans from two lasers allows you to immediately evaluate the quality of the scan:
The point clouds converged. Those. the planes captured by the two lasers converged over the entire surface.

Although from the very beginning I assumed that this was a dead end version that did not provide the necessary accuracy, I still tested it with various tricks:0023

The motor shaft is fixed with a bearing.
Added a friction element and a stopper for reducing gear backlash.
An attempt to determine the "exact position" by a phototransistor, by laser illumination

The repeatability of returning to the same place of the laser line was low - 2-3 mm at a distance of 1.5 meters. During the operation of the gearbox, despite the apparent smoothness, jerks of 1-3 mm are noticeable at a distance of 1.5 meters.

i.e. 28BYJ-48 is completely unsuitable for a more or less accurate large object scanner.

Reamer requirements based on my experience

Reamer must be a mandatory element.

Make no mistake about the 1/x step mode. Experiments have shown that in 1/16 mode on the A4988 the micro steps are not uniform. And at 1/8 this unevenness is noticeable to the eye.

The best solution for the gearbox was the use of a belt gear. Although it turned out to be quite cumbersome, it is easy to create and accurate.
The positioning accuracy (more precisely, the repeatability of the positioning of the initial position of the lasers for scanning) of the lasers turned out to be about 0. 5 mm for a 5 mm laser line width at a distance of 4 meters. Those. at a scanning distance (1.2-1.8 meters) it is generally difficult to measure.

Positioning - optocouplers (Chinese noname) on a slot in the disk under the lasers.

Problems with the transmission of control signals from the phone to the laser and stepper motor control module

The bottleneck in terms of scanning speed was the control channel. Since this was a DIY leisurely development for my own pleasure, we tried all the ways to communicate with a smartphone.

Transmission of control signals via Audio jack (phone Audio jack=> oscilloscope)

The slowest way to transfer data in real time. Yes, even with floating time. Up to 500 ms (!) from software activation of audio data transfer to the actual appearance of a signal in the Audio jack.

This exotic was tested because, at work, I had to deal with mobile chip card readers.

Photodiodes on the smartphone screen (a piece of the phone screen => phototransistors + STM32F103)

For the sake of interest, even such an exotic method was tested as phototransistors with a 2x2 matrix in the form of a clothespin on the screen.

Although this method of issuing information from the phone turned out to be the fastest, it is not so fundamentally faster (10 ms vs 50ms) than Bluetooth to put up with its shortcomings (a clothespin on the screen).

IR channel (phone=>TSOP1736->STM32F103)

The method of transmission through the IR channel has also been practically tested. Even some implementation of the data transfer protocol had to be done.

But IR also turned out to be not very convenient (it is inconvenient to mount a photo sensor on a phone), and not too faster than Bluetooth.

WiFi module (phone=>ESP8266-RS232->STM32F103)

The results of testing this module were completely discouraging. The request-response execution time (echo) turned out to be unpredictably floating in the range of 20-300 ms (average 150 ms). Why and what - did not understand. I just came across an article that talked about an unsuccessful attempt to use the ESP8266 for real-time data exchange with strict request / response time requirements.

i.e. ESP8266 with "standard" firmware TCP -> RS232 is not suitable for such purposes.

Selected control unit and signal transmission

Ultimately, after all the experiments, the Bluetooth (HC-05 module) channel was chosen. Gives a stable (and this is the most important) data transfer request-response time of 40ms.

The time is quite long and greatly affects the scan time (half of the total time).
But the best option was not achieved.

Widespread board with SM32F103C8T as control module.

Line detection methods on a frame.

The easiest way to highlight the laser lines on the frame is to use the subtraction of the frame with the laser off and the frame with the laser.

In principle, search by frame without subtraction also works. But it works much worse in daylight. Although this mode was left in the software for the sake of comparative tests (the photo of the mode is below. All other photos with the frame subtraction mode).

The practical value of the variant without frame subtraction turned out to be low.

It is possible and possible to extract the laser signal from this noisy information. However, he did not bother.

Frame subtraction works well.

All sorts of experiments with attempts to approximate the line and processing the entire frame have shown that the more complex the algorithm, the more often it "mistakes" and even slows down the processing "on the fly". The fastest (and simplest) algorithm was found to search for a laser (laser point) on a horizontal line:

For each line point, the sum of the squares of the laser color level (RGB) in the window specified in the configuration (13 px is the experimentally optimal value for the window) is calculated
Laser point - the middle of the window with the maximum value of the sums of the "color" levels.

The time for processing one frame by searching for the "green" and "red lines" is 3ms.

Point clouds for red and green laser are counted separately. With correct mechanical alignment, they converge with an accuracy of < 1 mm.

Accuracy and adjustment

The accuracy was within 1 mm at a distance of 1.2 meters. Mostly due to the resolution of the phone's camera (1920x1080) and laser beam width.

It is very important to make static and dynamic adjustments to obtain correct scans. The accuracy / inaccuracy of the settings is clearly visible when both point clouds are loaded into MeshLab. Ideally, the point clouds should converge, complementing each other.

Static parameters, set as accurately as possible once:

Tangent of the camera's field of view.
The length of the "shoulders" of lasers (from the center of the lens to the axis of rotation).

And of course, the maximum focusing of the laser lenses at a given scanning distance and the “verticality” of the laser lines.

The dynamic parameter of the actual position angle of the lasers relative to the virtual plane of the frame has to be re-adjusted every time the phone is mixed in the mount. To do this, the setup mode in the software is made. By bringing the lasers to the center of the screen and adjusting the angle, it is necessary to set the calculated distance as close as possible to the true (measured) distance for both lasers.

Before adjustment:

After adjustment:

Pins

Such a design, perhaps, can be repeated by anyone. I cut out all the details from fiberglass on the CNC.

Of course, without a CNC router, it is difficult to make a pulley for a laser. But taking into account the fact that you need a maximum angle of rotation of 90 degrees, then with due patience, the pulley can also be cut with a needle file.
