1. Shape of the resolution aperture of the camera tube was measured from the American RCA corporation, the effective amplitude response, asymmetry, the system which is defined with three parameters of MTF exponent was proposed resolution. 2. This chart is formed from the slanted stripe in order to obtain MTF exponent K and the slanted stripe in order to obtain the resolution aperture. As for the slanted stripe in order to obtain MTF exponent K, tilt angle of skew 30 degrees fixed is the stripe which is suitable to 100 - 600TV book. On the one hand, the slanted stripe in order to obtain the resolution aperture tilt angle of skew is the stripe which is suitable to the 400TV book of the degree of ±22.5, the degree of ±45, the degree of ±67.5 and 90 degrees vis-a-vis scanning line direction.
