Abstract
This paper presents a method of calibrating the stray light component of signal for imaging sensors by scanning the sun or moon. The advance of FPA detectors has enabled a variety novel small sensors for inferring atmospheric parameters. However, reflections off detector arrays can create a large component of stray light that must be removed from the total signal. Limb observations are particularly susceptible to stray light error. This paper presents a method of accurate numerical removal of stray light signal as a "function" of the measurement. We show that the "function" can be inferred from lunar or solar scans.
