径向分辨率测试图卡简介

1、有时候倾斜条纹导致解决成像设备功率上的差异，尤其是电视摄像管尽管是在同一情况下拍摄的电视画面。这要是因为椭圆孔状成像原理。

2、在径向分辨率图卡中，楔形条纹圆交替地用白色和黑色的分布。这张图卡是有位于200TV，400TV和800TV出的直径为1/1500H的圆形组成。

1.Sometimes slope of stripes causes a difference in resolving power of imaging device, especially pick up tube though the same number of TVs in a taken image. This is a phenomenon caused by an elliptic imaging aperture.

2.In Radial Resolution Chart, wedge-shaped fringes are circularly arranged alternately with white and black. The circles drawn by the line width 1/1500h are located in 200TV, 400TV and 800TV.(h is a height of a chart)
