In order to implement a convenient method to test the photochromic performance of laser projection display systems, the requirements corresponding to the laser display were investigated to satisfy the needs of design correction. On the basis of AVR microcontroller ATmegal28, a novel testing system for the photochromic performance of laser, projection display systems was designed by utilizing the laser characteristic of fixed wavelength. The detection of main photochromic performances such as luminous flux, uniformity of luminance and chrominance, and contrast ratio was realized. The detecting accuracy of the system is higher than that of the testing devices available.%为实现激光显示光色性能的精确检测,具体了解激光显示是否合乎相应的要求,从而达到修正设计的目的.利用激光波长固定的特点,基于ATmega128单片机设计并实现了一种专门针对激光显示光色性能的新型测试系统,从而实现了光通量、照度均匀度、色度均匀度、对比度等主要光色性能的测试.与目前各类检测系统相比,本测量仪采用独特的测试方法,精度高.系统验证结果证明,该单点测试系统可以低成本地实现光色性能的便携式且高精度测量,并可以移动地实现光通量、照度均匀度、色度均匀度、对比度等主要光色性能的精确测试.
