Laser Projector

The theater laser projector was built around a model 164 Spectra-Physics Laser Ion in 1970. The designers realized that could be the production of special mirrors are used to arrive on the same wavelength lasers, red, yellow, green and blue. The raw bar, a bar that had white eyes, he was a high index of refraction of the prism, which has drawn a distinction achieved by about two degrees between blue and red. With this technology, which generates the laser projector.

The original system of laser projection was locked in a relay cabinet located about 2 1 / 2 feet (approx. 0.76 m) square by 6 feet (1.83 meters) tall. Of course, the first laser projector large compared to a laser projector today. ½ inch (1.27 centimeters) thick aluminum plate segmented Cabinet laser projector home. The laser head, which was 4 feet (approx. 1.22 meters) long, was mounted vertically on one side of the plate. The laser head down.

The laser beam is reflected laser projector so through a hole on the opposite side of the plate. Optical equipment projector is mounted on this page. The laser beam blank in its component colors by a prism, a piece of glass or quartz material, which reflects the reflected rays. The four different colors are reflected acoustic rays through four optical modulators (AFSM), which varies the intensity of radiation by electronic means will be forced. These multiple frequencies from DC to more than 5 kHz, depending on demand.

The first image is generated by a laser projector was not clearly defined. With the changes in the projector-based lasers in recent years, however, the laser projector is now the heart of any graphics system.

Most projectors with Multi Color Full Color AFSM (PCAOM). This control of the cut and color laser projector. They are generally what is a "white" light beam been used to create color graphics. The new type of laser projector capable of things that I never entered the original creator to do.

With this type of laser projector, laser and white light in glass PCAOM right under a high frequency (HF) is injected from the tip. RF signal has a diffraction pattern, which acts like a prism.

Plan a laser projector is fundamentally sound and light together. The result is two bars on the left and the color desired. There is a good "waste" beam, all colors except the color. Together, these beams can be any image.
