21 May 2013 SUCHI: The Space Ultra-Compact Hyperspectral Imager for small satellites
Author Affiliations +
The Space Ultra Compact Hyperspectral Imager is a long wave infrared hyperspectral imager being built at the University of Hawaii. The sensor will be the primary payload on the HiakaSat small satellite scheduled for launch on the Office of Responsive Space ORS-4 mission, and planned for a 6 month primary mission which is extendable up to two years of operation on orbit. SUCHI is based on a variable-gap Fabry-Perot interferometer employed as a Fourier transform spectrometer and uses an uncooled 320x256 microbolometer array to collect the images. The sensor is low volume (16” x 4” x 5") and low mass (<9kg), to conform to the volume, mass, and power requirements of the small satellite. The commercial microbolometer camera and vacuum-sensitive electronics are contained within a sealed vessel pressurized to 1 atm. The sensor will collect spectral radiance data in the long wave infrared region (8-14 microns) and demonstrate the potential of this instrument for advancing the geological sciences (e.g. mapping of major rock-forming minerals) as well as for volcanic hazard assessment (mapping volcanic ash, quantification of volcanic sulfur dioxide pollution and lava flow cooling rates). The sensor is scheduled for delivery to the satellite in Spring 2013, with launch scheduled for Fall 2013.
