“…Those have to be totally depolarized (i.e., unpolarized illumination/intensity imaging), or totally polarized (i.e., polarized illumination/polarimetric imaging). One can note that this conclusion is similar to that obtained in the case when the signal is disturbed by additive Gaussian noise [10].…”

“…This will make it possible to determine for which scene parameters polarization imaging is preferable to standard intensity imaging, or active polarimetric imaging is preferable to passive polarization imaging. This issue has already been addressed in cases where the dominant source of noise is additive Gaussian [10], but it is the first time, to the best of our knowledge, that it is investigated in the presence of Poisson shot noise. Finally, the conclusions will be validated on simulated and real examples that show the importance to choose effectively the polarization states in illumination and analysis.…”

“…Hoover and his coworkers [14,15] have demonstrated that reduced dimensionality subspaces of Mueller matrix space can be used to perform invariant target detection through nonlinear model fitting. Goudail and his coworkers [16][17][18] have demonstrated that a singlemeasurement pMMP is optimal for maximizing contrast in a two-class detection problem with known class Mueller matrices.…”

Partial Mueller matrix polarimeters (pMMPs) are active sensing instruments that probe a scattering process with a set of polarization states and analyze the scattered light with a second set of polarization states. Unlike conventional Mueller matrix polarimeters, pMMPs do not attempt to reconstruct the entire Mueller matrix. With proper choice of generator and analyzer states, a subset of the Mueller matrix space can be reconstructed with fewer measurements than that of the full Mueller matrix polarimeter. In this paper we consider the structure of the Mueller matrix and our ability to probe it using a reduced number of measurements. We develop analysis tools that allow us to relate the particular choice of generator and analyzer polarization states to the portion of Mueller matrix space that the instrument measures, as well as develop an optimization method that is based on balancing the signal-to-noise ratio of the resulting instrument with the ability of that instrument to accurately measure a particular set of desired polarization components with as few measurements as possible. In the process, we identify 10 classes of pMMP systems, for which the space coverage is immediately known. We demonstrate the theory with a numerical example that designs partial polarimeters for the task of monitoring the damage state of a material as presented earlier by Hoover and Tyo [Appl. Opt.46, 8364 (2007)10.1364/AO.46.008364APOPAI1559-128X]. We show that we can reduce the polarimeter to making eight measurements while still covering the Mueller matrix subspace spanned by the objects.

“…(5). In Mueller polarimetry, in order to achieve optimal performance, one tries to make the DOP of the Stokes vectors generated by the PSG and PSA as close to 1 as possible [15]. If the extinction ratio of the linear polarizer in the PSG and PSA is high, the DOP of the generated states can be very close to 1.…”

We address calibration of Mueller polarimeters in transmission configuration and in the presence of noise. By comparing the maximum likelihood (ML) method and the extended eigenvalue calibration method, it is found that the ML method yields higher precision in the presence of noise. Moreover, we show that by employing the ML method together with simple constraints on the calibration matrices, it is possible to perform the calibration without using a retarder, and with only polarizers. This result is of great interest for the calibration of multispectral polarimeters.
