激光显示的原理与实现

基于三基色激光显示具有亮度高、色彩鲜艳、清晰度高等特点,给出了大屏幕激光显示技术的原理,介绍了本实验室应用波长分别为671 nm、532 nm和473 nm,功率为1.3 W,0.32 W和3.5 W的红、绿、蓝固态激光器制造的大屏幕激光彩色电视。针对激光显示中干涉散斑现象和颜色失真提出的瞬间小视场变波前消干涉方法和颜色扩展方法,在实验中取得了良好效果。

Principle and realization of laser display technique

The principle and technique to realize laser color video display were introduced. A large screen laser color display system was proposed on the basis of the blue, green and red diode pumped solid state lasers at wavelengths of 473 nm, 532 nm and 671 nm,the output powers of 1.3 W, 0.32 W and 3.5 W, respectively. The technical approach was presented to eliminate the laser interference, improve the uniformity of optical field, transform the chromaticity and extende the virtual color. The experimental results show that the laser projection display can agree with design well in fully saturated colors, higher contrast ratio and high resolution.
