A Method for Measuring the Spatial-Frequency Response of a Television System

A simple method for obtaining quantitative measurements of the dynamic response of a television chain to spatially distributed light input signals is described. The major improvement over existing techniques is in the method of scanning the target and the ability to make rapid quantitative measurements of the system's response to almost any spatially distributed input light signal. The measurement of a television system's response to spatially distributed light input signals such as sine waves, square waves, step or impulse signals is described and/or illustrated. Adaptation of this technique for measuring the line-profile and interlace factor of a picture tube is also described. The apparatus required for these measurements is available in most well-equipped television laboratories and the measurement procedure is not unfamiliar to television engineers.
