Resumen:
A spatially adaptive Mueller matrix imaging polarimeter is described,
simulated, and demonstrated with preliminary experiments. The system
uses a spatial light modulator (SLM) in the polarization state generator
(PSG) to create spatial carriers that controlled by the pattern written
to the SLM. The polarization state analyzer (PSA) is a commercial
division of focal plane imaging polarimeter. The PSG/PSA pair form a
9-channeled partial Mueller matrix polarimeter that measures a 3 x 3
sub-matrix of the Mueller matrix. We demonstrate that adapting the PSG
modulation to the spatial frequency structure of the scene can reduce
channel crosstalk and improve reconstruction accuracy. Initial
experiments are performed that demonstrate the SLM's ability to produce
sufficient modulation diversity to create the desired channel structure.
Though there are several experimental challenges to obtain accurate
Mueller matrix imagery, we demonstrate a system that adapts to the
particular scene spatial frequency structure. & COPY; 2023 Optica
