|Title:||Stray light correction algorithm for multi-spectral hyperspectral spectrographs|
|Published:||June 01, 2012|
|Abstract:||An algorithm is developed to correct a multi-channel fiber-coupled spectrograph for stray or scattered light within the system. The efficacy of the algorithm is evaluated based on a series of validation measurements of sources with different spectral distributions. This is the first application of a 2-dimensional scattered light correction algorithm to a multi-channel spectrograph. The algorithm, based on characterization measurements using a tunable laser system, can be extended to correct for finite point-spread response in imaging systems.|
