径向分辨率测试图卡简介

　　径向分辨率测试图卡TE157用于检查摄像机的径向分辨率，测试图卡显示具有180个扇区的扇形星。 一个扇形对应于2°的角度，并且具有黑色和白色光束。

　　扇形星的中心显示白色圆形区域。 在该核心的边缘，扇区宽度对应于相对于测试图的宽度(由灰色箭头标记)的10MHz的频率。 附加的白色同心圆标记(在外边缘上)以下频率：8,6,5,4,3和2MHz。

　　Radial resolution test card

　　Radial resolution test card TE157 is used to check the radial resolution of the camera. The test card shows fan-shaped stars with 180 sectors. A fan corresponds to an angle of 2 ° and has a black and white light beam.

　　The center of the fan-shaped star shows a white circular area. At the edge of the core, the sector width corresponds to a frequency of 10 MHz relative to the width of the test pattern (marked by a gray arrow). Additional white concentric circles (on the outer edge) the following frequencies: 8, 6, 5, 4, 3 and 2 MHz.
