A study of high definition display and measuring laser system

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.
