Paper Abstract

The specifications and performance are set forth for a multispectral linear array developed for SWIR remote sensing applications. The device comprises a monolithic quadruple-band image sensor with 4096 detectors in each band. The silicon Schottky barrier IR CCD has been utilized for the SWIR sensor. Operating at temperatures from 77 k to 82 k, the device also employs a SiC-Al2O3-SiC-based package constructed with epoxy adhesives, and four narrow bandpass filters attached to the device. A performance study shows that the dynamic range is 2500 with a noise floor of 74 electrons rms, and the signal to noise ratio is 41.6 dB for an irradiance of 9.4 microwatts per square centimeter, at a wavelength of 2.06 microns and an integration time of 3.46 ms. The response of the device demonstrates a nonuniformity of 6.4 percent peak-to-peak. The sensor is intended for the Japanese Earth Resources Satellite-1.
