摘要
激光扫描显示有两种方式:矢量扫描和光栅扫描。从原理、应用场合和发展前景等方面对这两种扫描方式进行了比较。着重分析了单色光束的光栅扫描理论。借鉴传统电视扫描原理,推导出光栅扫描参数之间的关系式、光栅亮度表达式及光束调制性能参数表达式。最后,对一些参数进行了讨论并给出了讨论结果。
There are two types of laser scanning display, vector scanning and grating scanning. A comparison between the two scanning modes in the aspects of principles, application and prospects for development is made.The paper studies the principle of homochromous beam grating scanning.With reference to traditional TV,relations of the grating parameters, expressions of the brightness and modulation parameters are deduced. At the same time, these parameters are discussed.
