摘　　要：由于激光准确的波长,可以精确确定其在颜色匹配曲线上的数值。基于激光的这一特性,提出了一种新的光色性能的测量方法和系统。该系统充分利用了激光显示的优势,色度探头采用双通道反馈放大回路切换,并在PC中建立数据库存储数据,它配有GUI界面,极大地方便了不同用户的使用。实验结果证明该系统可以低成本实现光通量、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。A new system to measure the light performance which relies on the accuracy of the laser wavelength is developed.Based on the advantage of laser display,the chrominance probe of the system is designed to switch between dual-channel-feedback-amplifying-circuit,while the data is saved in the database in PC which can be used by various users for it has GUI.The results demonstrate that this low cost system is capable of accurately measuring main light color properties such as the uniformity of luminance,chrominance,and contrast ratio.
