Abstract
A laser acoustooptical system for projecting TV images onto a large-area screen is developed and produced. A copper-vapor laser with an average power of 20 W is used in it as a radiation source. Images are formed by using green and orange spectral lines. The exposure of a whole TV line on a screen in a time corresponding to the laser pulse duration is the principle governing the operation of the system. A TV line is formed by an acoustooptical modulator (AOM) designed on the basis of a paratellurite (TeO2) crystal. Frame scanning of an image is performed by using an electromagnetic galvanometer. A high line and frame resolution of about 2000×1000 pixels in the TV standard is obtained. The system makes it possible to form a TV image of size greater than 20 m2 with brightness of about 50 cd/m2 at a distance of 20 to 100 m. Operating principles of the system and requirements imposed on the laser, the AOM, and other elements are considered.
