Abstract :
An alternative way of generating the pedestal current in a pyroelectric vidicon (p.e.v.) is described. The better uniformity of the pedestal current gives less flicker when the p.e.v. is used in the 25 Hz chopper mode. A more uniform tube response is expected, being useful when temperature measurements, based on the local video level, are made.
