DNP RCA P-200解像度测试卡 4:3

RCA P-200解像度测试卡简介

1、根据美国无线电公司（RCA）提出的三个参数实际振幅反应、非对称性和MTF指数定义的分辨率，以测量电视摄像管的分辨率光圈的形状。

1.Radio Corporation of America(RCA) proposed to define resolution by three parameters, effective amplitude response,asymmetry postulate and MTF index, with measuring the shape of resolution aperture of pick up tube.

2、这张测试图卡由为了得到MTF指数K值设定的斜条纹和为了得到解像度光圈而设定的斜条纹构成。为了得到MTF指数K值设定的斜条纹相当于28～1500TV  MTF。

2.This chart consists of sloped fringes to find MTF index ‘K’ and sloped fringes to find resolution aperture. The sloped fringes to find MTF index ‘K’ are equivalent to fringes of 28 to 1500TV MTF.
