What is a laser projector?

Theater laser projector was built on the Spectra-Physics Model 164 laser at the beginning of the 70s. The designers realized that special output mirrors can be used to make lash simultaneously in red, yellow, green and blue wavelengths. A raw beam, a beam that looked white to the eye, was shot with a high prism of the refractive index, which reached the separation of about two degrees between blue and red. It was with this technology that a laser projector was created. Needless to say, the first laser projector was huge compared to today's laser projector. The fleece aluminum plate was cut off from the cabinet of the original laser projector. The laser head, which was 4 feet long (about 1.22 meters), was mounted vertically on one side of the plate. Laser head POINDED.

The laser beam of the laser projector was then reflected through the opening on the opposite side of the board. To tThe side of the projector's optical equipment was mounted. The white laser beam was fired in its component colors with a prism, which is a piece of glass or quartz material that reflects rays. The four individual color rays were then reflected through four acoustic optical modulators (AOM), which forced the intensity of the individual beams to change electronically. This changed the frequency from DC to more than 5 kHz depending on the need.

The first picture created by the laser projector was not well defined. However, with changes that have been made over the years on the basic laser projector, the laser projector is now the core of any graphical system.

Most fully color projectors use polychromatic aom (PCAOMS). This control and color selection in a laser projector. They are usually used with what is referred to as "white light" rays to create fully color graphics. A new type of laser projector is able to do things that originsThe creators never touched.

With this type of laser projector, the laser beam of white light enters the right crystal, while the radio-frequency signal (RF) is injected from above. The RF signal sets a diffraction pattern that acts as a prism.

The

laser projector is basically healthy and plays light together. The result is two rays protruding on the left and become the desired color. There is also a "waste" beam containing all colors except the desired color. Together, these light rays can create any desired image.
