ABSTRACT:
A thermal detector is made from a pair of electrodes and a plastic material disposed therebetween which material has a polarization sensitive to IR radiation. Preferably the detector is formed on a substrate with the plastic material being deposited by spin-casting. The material is a copolymer of TrFE and PVDF. The detector may be partitioned into an array of sensors and used in an apparatus wherein the image of an object is projected onto the array and a chopper is used to block the image from the sensors at regular intervals.
