Infrared Imaging Device.

Abstract

The patent application relates to a pyroelectric infrared camera system which employs chopping plus image-difference processing. A pyroelectric vidicon is scanned at some frame rate and chopped at one-half that rate, generating frames having alternating scene polarity. Each frame is stored in a video disc recorder, the following frames subtracted therefrom and the resultant signal displayed (after inverting the polarity of alternating frames).
