Spectral observation using a Hyperspectral Imager
The Hyperspectral Imager goes above and beyond taking a simple image. What we view with our eyes includes a lot more information than currently is captured in a traditional image; and using interferometry we are able to gather some of that lost information and include it in an image.  You see green, we see camouflage!  Problems of image to fringe quality, shadow/intensity issues, and 'filtering' unwanted information need to be tackled and solved to obtain the best working system possible.  Spectrums from gas discharge tubes have been studied as well as chlorophyll and laser light to obtain a spectrum that is accurate.  Applying scanning techniques we plan to obtain the spectrum in any desired pixel of an image accurately and quickly.
