A Flash Hyperspectral Imaging System for Astronomical Applications Jim Scholl, UA Coll. Of Optical Sci. / CAAO • Views target scene through 2D grating and sorts out overlaps in post-processing. • True, non-scanning, snapshot (x, y, l) imaging of a hyperspectral object cube. • Inherent spatial co-registration. • Trying to validate astronomically useful calibration – observations underway in HI. • Systems in Visual, SWIR, MWIR, LWIR wavelengths l = 420 to 735 nm Simulated FPA data from telescope Tomographic Reconstruction Using Matched Filtering in either Fourier or Wavelet Space.
