2009-2019 Outdoor lasers


The laser videoprojector OUTDOOR LASERS is a modern optoelectronic acousto-optical device for outputting laser graphics and video information. The projector is equipped with a built-in video server (miniPC based on Windows OS) and broadcasts video streaming either from the built-in computer screen or from the HDMI input port. No pre-video training is required. At the moment, the resolution of the projector in different models ranges from 300 to 900 pixels in one coordinate, with interlaced scanning at a frequency of 60 to 120 Hz.

The projector can be controlled over the network using either the RG-45 connector or via WiFi. The second way is to connect an external monitor to a VGA or HDMI port and use a USB mouse and keyboard.

The projector uses two two-coordinate acousto-optical deflectors. (Without the use of mechanical scanning and DLP matrices).

The projection distance is from several meters to one and a half thousand meters (1.5 km). In this case, the area of ​​the projection reaches up to 1000 square meters. meters. (The exact areas are listed below for all models). In this case, do not forget that the brightness and area of ​​the projection strongly depend on the background lighting and the type of the projection surface. The ideal surface is a white stucco wall or white brick, but the crowns of trees, and the lawns of stadiums, and the towers of boiler houses, fences, asphalt, and especially the facades of houses.

The projector has a built-in thermostating system. Thus, it can work both at high and low temperatures without additional conversion. The thermostating system includes a system of internal and external radiators, thermoelectric elements, air coolers and contour switching valves. Working liquid - antifreeze (ethylene glycol). All models were tested in the temperature range from -35 ° C to + 35 ° C.

The external optical windows are covered with a hydrophobic coating, which allows several thousand glass cleaning cycles without sacrificing the antireflection coating.

The typical name of the model looks, for example, Outdoor lasers G8.2. The first letter in the model name indicates the color of the laser module: G-green, B-blue, R-red. Other colors are available on request, for example, orange, yellow or light green. (The exact wavelength is listed below in the technical description for each model). The first digit in the model name indicates the maximum output optical power of the laser source of radiation in watts (W).

The second number in the title indicates the number of independent playback channels. In the models of this series there are always 2. Each channel can project independent content on the same or different screens. The size and shape of these screens is also independent. It is possible to sew the two screens horizontally, vertically and in random order, and also duplicate the same image on them. At the same time, all the light brightness is concentrated in those points that are now displayed, thereby increasing the brightness of the picture. This means that by reproducing fragmentary illumination, you can greatly increase the brightness of the projection and even project in the daytime, but with certain restrictions on the content.


The optical scheme of the projector is arranged so that after adjusting to infinity, the image remains in focus at the entire distance. And the projection angle lies in the range of ± 60 °, and maybe even more. Just because of this feature, it is possible to create 3D video on the asphalt. The projector can easily be placed on the roof of an adjacent building, on a tower or tower, from any position, you can programmatically defeat all geometric distortions.

The color projector can use two, three or even more color channels. In principle, each channel is configured separately, and you can even make three separate monochrome screens. But to create a color picture you need to reduce all three colors on the projection surface. This is done in two stages: beginning mechanically optics, all three channels are reduced to approximately one area, and then programmatically, all three screens reduce the pixel to a pixel. It turns out that colors blend only directly on the projection surface, perhaps this fact will leave you indifferent, but this fact is worth it to realize it. The automatic color distribution system is now in the beta testing process.

The laser projector is suitable both for a single installation, and for creating a projection media facade from several projectors. The energy consumption of lasers is several times less than the consumption of lamps, so even the most powerful our projector consumes less than 1 kW.
