徑向分辨率測試卡簡(jiǎn)介

1、有時(shí)候傾斜條紋導致解決成像設備功率上的差異，尤其是電視攝像管盡管是在同一情況下拍攝的電視畫(huà)面。這要是因為橢圓孔狀成像原理。

2、在徑向分辨率圖卡中，楔形條紋圓交替地用白色和黑色的分布。這張圖卡是有位于200TV，400TV和800TV出的直徑為1/1500H的圓形組成。

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)
