激光光阀大屏幕显示是七十年代发展起来的一项新的显示技术。由于它采用激光器做记录光源,所以记录片上的分辨率可以做得很高;同时它采用外光源照明和光阀式投影,因此屏幕上的亮度和对比度也非常高,显示屏幕可做得很大。它采用高精度的扫描器——振镜,使随机扫描的精度满足了实际使用的要求。激光光阀大屏幕显示是一种先进的显示技术,它不但可用于军事指挥系统,也可用于民用;把投影系统去掉后,也可用于电子
Laser light valve large screen display is developed in the seventies a new display technology. Because it uses a laser as the recording light source, the resolution on the recording sheet can be made high. At the same time, it uses external light illumination and light valve projection, so the brightness and contrast of the screen are also very high, the display screen can be done very large. It uses a high-precision scanner - galvanometer, so that the accuracy of random scanning to meet the actual requirements. Laser light valve large screen display is an advanced display technology, which not only can be used for military command system can also be used for civilian use; the projection system removed, can also be used for electronic
