Abstract

A technique is described whereby as is Moire interference pattern is produced by a cathode ray tube (CRT) electron beam so as to provide a visual indication of non-linearities. The Moire's pattern reveals minute and hidden periodicities, which provide a check of the deflection of the beam.
