Abstract

The Hughes Aircraft Company CRC-365 is a hybrid infrared focal plane array that features a 256 X 256 array of platinum silicide (PtSi) photodiodes. The device was tested in a laboratory environment to determine its performance limits, in the context of MWIR imaging. Test results included the dc transfer function of the multiplexer, power dissipation, dark current, thermal barrier height, Schottky barrier height, blackbody response, saturation charge, signal contrast, Schottky quantum yield, temporal noise, NETD, response nonuniformity, temporal drift, and MRTD. Overall, performance was found to be excellent. Using two-point nonuniformity correction, background-noise-limited photodetection was achieved for a 40 degree target temperature range. Notable problem areas included bandwidth limitations and electrical crosstalk.
