1、根據美國無線電公司（RCA）提出的三個參數實際振幅反應、非對稱性和MTF指數定義的分辨率，以測量電視攝像管的分辨率光圈的形狀。
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、這張測試圖卡由為了得到MTF指數K值設定的斜條紋和為了得到解像度光圈而設定的斜條紋構成。
為了得到MTF指數K值設定的斜條紋相當于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.
