Abstract

Commercial Hyperspectral Imaging (HSI) systems capable of both fine spatial ground resolution and high signal to noise ratio pose challenges to the integration and testing process. The following will describe methods developed for a Low Earth Orbit (LEO) system having an effective focal length of approximately one meter and a ~f/2 optical speed. Internal subsystem testing is outlined as it relates to full-system performance. A sub-aperture testing routine is described to establish baseline performance estimates for spatial and spectral characteristics at a system level. Analysis and testing results are presented as measured during the integration process.
