基于CCD照度采集合成白光色均匀性测量及分析

介绍投影显示系统的色度均匀性测试的单点法，提出了基于CCD照度采集的多点测试法．详细阐述了基于CCD照度采集的多点测试法的测试原理、系统构成及实现过程．给出了该测试方法对DLP投影系统的三色及合成白光的均匀性测试结果，并分析了其成因．最后比较了多点法与单点法的测试结果及所需测量时间．得出的结论是多点法的测试结果较单点法具有客观性和科学性，而且多点法所需的时间要远远小于单点法所需的时间．

The Analysis and Survey of White Color Illuminztion Uniformity Mixed by CCD-based Collection

This paper introduces the single - point test method used in surveying of enhanced chroma uniformity in the technology of displaying Projection type, and proposes the test method of multi - point based on CCD illumination collection. This paper Elaborate in detail the principle of the test method of multi -point based on CCD illumination collection, composition of the system and implementation procedure. The test method is given to the test results of the uniformity of tri - color and mixed white light in DLP projection system and analysis of its reason. Finally, compared with the result and using time of the single - point test method, the outcome of multi -point method is objective and scientific, and much less the time required.
