“…The sample range is 73 cm; thus, the system aperture angle is 4.3 mrad. • Spectropolarimetric reflectometer 13 : This is a labbased, dual rotating retarder polarimeter based on a Fourier transform spectrometer. The system can operate in a bistatic or monostatic configuration and uses different light sources ͑incoherent͒ and detectors to extend its wavelength range from the UV to approximately 25 m. The system has a 25.4-mm diam entrance pupil and a 63.5-cm sample range; thus, its aperture angle is 20 mrad.…”

Influence of sensing geometry on polarimetric reflectance data

Our objective is to disseminate the importance of sensing geometry when comparing reflectance data from different polarimeters. Results are presented from an eye-safe laser scatterometer that was used to measure the Mueller matrix of samples under a diversity of sensing geometries, thus providing a common reference for instrument comparison. Data from three other polarimeters are compared to this reference, and apparent discrepancies are explained in terms of each instrument's unique experimental sensing geometry. Results are also provided showing that the degree of sensing geometry dependence varied widely among sample types.
