Abstract

We present a highly integrated payload suite which consists of the following instruments: a hyperspectral imager covering the wavelength range from 0.7 μm up to 5μm, and a thermal infrared radiometric imaging spectrometer. The payload design is the result of a design study that was performed in the context of the development of space exploration technologies under ESA contracts. The payload is broadly applicable to environmental research and for a number of remote sensing mission scenarios. All instruments have imaging capability and have been chosen such that they profit from close integration. HIBRIS is a combination of the hyperspectral NIR spectrometer, considered as generic instrument being part of many missions, and the radiometric micro-bolometer in the thermal infrared spectrum. A linear variable filter (LVF) concept is implemented in the NIR range that avoids the use of gratings which are usually limited to one decade of spectral range or less. The thereby rather compact design does allow the integration of multiple instruments within a rather limited volume envelope. The suite also makes use of a microcooler and the most advanced NIR detector technologies. The use of an LVF drives the spectral resolution of the instruments to 1% of the wavelength. The SNR is satisfactory in the most part of the spectrum for LEO EO missions. Current activities at cosine Research have focused on the design and performance of uncooled microbolometers, linear filters, light shielding baffles, beam splitters for shared optical paths, and the thermal design of HIBRIS.
