In the frame of technological preparation for scientific Earth observation, the European Space Agency (ESA) has undertaken a study program for a hyperspectral imager to be implemented on a low Earth orbit type satellite: HRIS (high resolution imaging spectrometer). The instrument is a pushbroom operating near 800 km altitude sun-synchronous orbit with 40 m sub-satellite spatial sampling, 30 km swath variable by plus or minus 30 degrees and a spectral coverage from 450 to 2350 nm at 10 nm average spectral sampling. One of the major challenges is therefore to develop, implement and operate a SWIR 140 multiplied by 768 pixels array tailored for the mission requirements, with main emphasis on low noise and high linearity over a large dynamic range. A SWIR focal plane breadboard has been studied and developed to be operated in the 1 to 2.35 micrometer range with the intention of demonstrating both performances and buttability. The hybrid technology is based on photovoltaic, HgCdTe buttable diode arrays coupled to full custom CMOS silicon multiplexing circuitry. Due to system constraint and as a result of trade-of at performances level, the focal plane is operated at 150 K. A similar SWIR focal plane (140 multiplied by 1024 pixels) is also intended to be the baseline in the frame of the ESA PRISM instrument (processes research by an imaging space mission).
