Abstract

Staring infrared focal plane arrays with epitaxial HgCdTe photovoltaic detectors coupled to surface channel CCD multiplexers have been fabricated and characterized. A source-coupled input circuit with background suppression is utilized. The HgCdTe backside-illuminated detector arrays have bandgaps suitable for operation in either the 3 - 5 or 8 - 12 μm region. Performance characterization of the multiplexer will be given at cryogenic temperatures. Charge transfer efficiency, subthreshold transconductance, threshold voltage temperature dependence, and 1/f noise measurements will be presented. These measurements will be compared with ideal models. Characteristics of the hybrid focal plane have been measured in a wide variety of backgrounds. Data will be presented on the noise characteristics, detectivity and noise equivalent temperature difference in backgrounds and temperatures suitable for passive thermal imaging.
