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.
