Abstract

To examine the polarimetric Bidirectional Scatter Distribution Function (BSDF) of samples in the mid-wave infrared (MWIR) and long-wave infrared (LWIR), a full Stokes polarimetric optical scatter instrument has been developed which is tunable from 4.3-9.7 microns through the use of six external-cavity quantum-cascade lasers. The polarimeter is realized through a dual-rotating-retarder configuration, which allows full Mueller-matrix extraction over the tunable wavelengths. Optical characterization of the polarimeter components was conducted to establish performance baselines for the system. The dynamic range of the system is nine orders of magnitude.
