摘要
文中从投影管荧光屏与光路两方面对影响亮度均匀性的因素进行分析,得出光路是影响亮度均匀性的主要因素,而投影管的亮度不均匀可以对此起到一定的补偿,并据此提出了进行亮度不均匀校正的方法。
In this article, takes care of both projection tube and optics processing. It concludes that optics processing is the main reason of the asymmetric illumination distrbution and that projection tube partly compensates the influence of optics processing. Then the research of correct method is raised.
