近代技术的发展,使激光束的调制和扫描在速度上能与用于电视接收机的电子束相比。它不象阴极射线管那样必须封入有限大小的真空中,因此,目前人们对激光显示系统产生较大的兴趣。本文的目的是要说明利 The development of modern technology has enabled the modulation and scanning of the laser beam to be faster than the electron beam used for the television receiver. It does not have to be enclosed in a vacuum of finite size like a cathode ray tube. Therefore, there is a great interest in laser display systems. The purpose of this article is to illustrate the benefits
