Advanced Technology Land Imaging Spectroradiometer

The Advanced Technology Land Imaging Spectroradiometer (ATLIS) is a small (0.04 m3), multispectral pushbroom imager designed to provide visible through shortwave (VSWIR) calibrated imagery for the baseline Sustainable Land Imaging-Technology (SLI-T) reference mission architecture (RMA). ATLIS is designed to provide imaging spectroradiometry that meets or exceeds SLI-T RMA key parameters [1] with an instrument that is much smaller and much less massive than previous land imaging systems. This paper reports on results from a NASA ESTO funded project to design, build and test a six spectral band prototype ATLIS called ATLIS-P and demonstrate whether this compact, low mass design approach with wide field of view (WFOV), free form reflective telescope, large format, small detector digital FPA and on-chip processing meets or exceeds SLI-T RMA VSWIR requirements.
