Paper Abstract

Results are presented on the performance of Schottky-barrier focal plane arrays operating in selected spectral bands. The devices measured were monolithic PtSi Schottky diode arrays, 64 X 128 elements, with buried channel CCD readout. The arrays were fab-ricated by RCA Laboratories, Princeton, New Jersey, under a contract from RADC/ESE for the development of high density focal planes. The spectral bands of interest were chosen in an attempt to determine the optimum filtering (spectral) for operation in day/night conditions with minimum interference from sun light or high clutter environments. The measurements were performed in both working thermal imaging camera systems and in laboratory dewars modified to accomodate filters for the desired spectral bands. Data are presented on the transfer characteristics and in-band thermal responses as well as the quantum yield of the devices. Conclusions about operation in the spectral bands chosen and comparison with broad band data are discussed. Examples of the high quality imagery obtainable with these devices are shown.
