A Programmable Hyperspectral Imager for Space Applications

Abstract

Hyperspectral imaging is a valuable tool for earth observation, with a broad range of applications. For the large majority of satellite-based hyperspectral imagers, the 3 dimensional hyperspectral cube is recon- structed from multiple acquisitions of a 2D detector array. Most of these imagers have a 1D field-of-view so the detector array acquires the spatial data in one direction and the spectral components in the other [1]. The satellite movement is used to acquire the second spatial dimension of the hyperspectral cube. This method of acquisition is straightforward but the light flux received by the detector is low due to the entrance slit defining the field-of-view.
