Paper Abstract

Self-scanning pyroelectric infrared detec tor arrays (32 and 128 elements on 100 μm center-to-center spacing) have been developed and characterized. The detectors consist of a monolithic crystal with in dividual elements deliniated by photo-etched electrodes. They are coupled to an integrated circuit array of self-scanning FET multiplexing switches, mounted in the same IC package with the detectors, for periodic signal readout. Current applications are instantaneous beamscans for infrared lasers, high resolution detec-tors for real time spectroscopy, and un cooled operation for thermal imaging. Pulsed and chopped CW radiation applications are to be discussed, as are timing requirements, sensitivity, dynamic range, and circuit considerations.
