Paper Abstract

The operation, performance, and applications are set forth for linear and area focal plane arrays which use PtSi Schottky barrier diodes to image in the 1 to 5.5 micron spectral range. Two linear FPAs, with pixels spaced on 25 micron centers, are considered. A digital scan readout is used in these arrays. A discussion of a 128 by 128 element PtSi FPA follows, where a MOS/CTD readout structure is employed. The digital shift register addresses diode rows one by one due to the parallel connection of the MOS multiplexer switches in this device. Two bucket brigade charge transfer registers are utilized for signal readout. Lastly, a high fill factor, low noise 512 by 512 PtSi FPA is discussed, which uses a new line-addressed charge-accumulation (LACA) CCD in an interline transfer configuration and a multiple-readout horizontal register. The digital scan readout allows high sensitivity and signal levels. The second device and the LACA structure permit a high fill factor and charge handling capacity. The lower cost and higher resolution of the latter devices are underscored, and applications for all the FPAs are listed.
