Laser Projector

The theater laser projector was first built in the early 1970s. Designers learned that special output mirrors could be used to allow lasing to occur simultaneously at red, yellow, green, and blue wavelengths. The raw beam, a beam that appeared white to the eye, was shot with prism, which achieved a separation of about two degrees between blue and red. It was with this technology that the laser projector was created. The first image produced by a laser projector was not well defined. However, with the changes that have been made to the basic laser projector over the years, the laser projector is now the core of any graphics system.

LCD Projector

In an LCD projector polarized light is transmitted through an LCD panel. The LCD panel modulates the polarization of the light according to the desired image data. The modulated light then passes through another polarizer, or an analyzer, to form the desired image. The image is magnified and reformed for display on a screen.

Laser Stars Projector

Laser stars projector is a unit about 10 inches tall that projects a combination of green laser stars and blue clouds onto your ceiling, walls, pets, etc. The clouds and the stars are constantly moving and morphing, just like a Universe should. There are thousands of green laser stars to look at. There are two ways for you to adjust your laser stars projector. First you can pivot it 180 degrees horizontally around the base so that you can control where it is projecting in your room. It can actually fill up an entire ceiling and parts of several walls simultaneously. And the other thing you can adjust is the intensity of the blue gaseous clouds – from zero to full intensity.

One of the most crucial components of the laser star projector is the laser itself. In the past a mixed gas laser was most commonly used. These lasers could produce several colors simultaneously but were difficult to use. Gas lasers have been replaced by solid state lasers, like the fireball laser projector. Most solid state laser projectors are green, red and sometimes blue.
