Investigation on Laws of 2-D Laser Scanning

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.
