Claim Text:
1. A system for characterizing polarimetric response of an optical instrument comprising: a light source for emitting light along an optical axis, at least one of first and second polarizers disposed perpendicularly to the optical axis, for receiving light emitted from the light source, a spectral filter and an optical detector, defined as a first sub-system, for receiving light transmitted through the at least one of the first and second polarizers, and an optical instrument, defined as a second sub-system, selected to replace the first sub-system, for receiving light transmitted thorough the at least one of the first and second polarizers, wherein the first and second polarizers are disposed perpendicularly to the optical axis, and the first sub-system is configured to obtain a first set of measurements based on the light received through the first and second polarizers, the first polarizer only is disposed perpendicularly to the optical axis, and the second sub-system is configured to obtain a second set of measurements based on the light received through the first polarizer, the second polarizer only is disposed perpendicularly to the optical axis, and the second sub-system is configured to obtain a third set of measurements based on the light received through the second polarizer, and the first, second and third sets of measurements are effective for characterizing the optical instrument.
