Laboratory characterization of HYPSOS, a novel 4D remote sensing instrument
The HYPerspectral Stereo Observing System (HYPSOS) is a novel remote sensing pushbroom instrument able to give simultaneously both 3D spatial and spectral information of the observed features. HYPSOS is a very compact instrument, which makes it attractive for both possible planetary observation and for its use on a nanosat, e.g. for civilian applications. This instrument collects light from two different perspectives, as a classical pushbroom stereocamera, which allows to realize the tridimensional model of the observed surface, and then to extract the spectral information from each resolved element, thus obtaining a full 4-dimensional hypercube dataset. To demonstrate the actual performance of this novel type of instrument, we are presently realizing a HYPSOS prototype, that is an instrument breadboard to be tested in a laboratory environment. For checking its performance, we setup an optical facility representative of a possible flight configuration. In this paper we provide a description of HYPSOS concept, of its optomechanical design and of the ground support equipment used to characterize the instrument. An update on the present status of the experiment is finally given.

Giampiero Naletto is Associate Professor in Experimental Physics at the University of Padova; since 2010 he has been Director of the PhD Course on “Space Sciences, Technologies and Measurements” at the same University. He has concentrated his research activities on the realization of innovative optical instrumentation, mainly but not exclusively for space and ground astronomical applications. He has contributed to the development and realization of several instruments for both NASA and ESA missions, as UVCS on SOHO, FUSE, the OSIRIS imaging system on Rosetta, the Simbiosys imaging system of BepiColombo, and Metis on Solar Orbiter. He is co-author of more than 400 publications on international Journals and Conference Proceedings.
