|Title:||Stray-Light Correction Algorithm for Spectrographs|
|Published:||February 01, 2003|
|Abstract:||In this work, we describe an algorithm to correct a spectrograph's response for stray light. Two recursion relations are developed: one to correct the system response when measuring broad-band calibration sources and a second to correct the response when measuring sources of unknown radiance. The algorithm requires a detailed understanding of the effect of stray light in the spectrograph on the instrument's response. using tunable laser sources, a dual spectrograph instrument designed to measure the up-welling radiance in the ocean was characterized for stray light. A stray light correction algorithm was developed, based on the results of the laser-based measurements. The instrument's response was corrected for stray light and the effects on measured up-welling in-water radiance evaluated.|
