一、扁形黑白显象管产生光栅畸变的原因 扁形显象管的结构特征是将电子抢放置在荧光屏的侧面。显示图图象时,电子束平行于荧光屏面射入,通过特殊的电子光学系统最后打在荧光屏面上产生图象光栅。以下分析扁形显象管产生光栅畸变的原因和校正的方法。
First, the flat black and white picture tube causes raster distortion The characteristics of the flat picture tube is placed on the side of the electronic screen grab. When the image is displayed, the electron beam is incident parallel to the phosphor screen and the image grating is created by striking the phosphor screen through the special electro-optical system. The following analysis of flat CRT tube raster distortion causes and methods of correction.
