Abstract

This memorandum describes a semi-automatic facility which directly plots the dynamic modulation transfer function of cathode ray tubes. A sine-wave pattern is generated which moves at a chosen rate across the screen. The intensity of the spatial pattern is measured by a stationary optical detector. Some discussion is given of the potential of pulse output signal processing to determine the ultimate performance capability. The high signal to noise ratio obtained is illustrated by some preliminary results.
