“…It is well-known that 4 n = modulation states is the least number to demodulate the incident Stokes vector. Division-of-aperture and division-of-focal-plane snapshot imaging polarimeters usually employ four modulation states to achieve maximum spatial resolution on a single array detector [46][47][48][49][50]. For the optimization metrics CN, EWV and PME, there is an optimal retarder and rotator combination as pointed in reference [25,[38][39][40][41].…”

Abstract:In this paper, the design, optimization and analysis of broadband full-Stokes polarimeters with immunity to both Poisson and Gaussian noise are presented. Different from the commonly-used optimization metrics such as, the condition number (CN), the equally weighted variance (EWV), or the polarimetric modulation efficiency (PME) for Gaussian noise, the optimally balanced condition for Poisson noise (BCPN) is, for the first time, proposed and used as a metric for the optimization of polarimeters. The numerical results show that the polarimeters optimized with the BCPN have immunity to both Poisson and Gaussian noise. The broadband polarimeters optimized from the BCPN are achromatic and have similar polarimetric modulation properties over the waveband, in contrast to the polychromatic polarimeters optimized from the CN, EWV and PME, whose polarimetric modulation properties vary with wavelength.

“…The solid body that is spanned by these four optimal polarization measurements is a tetrahedron, and this construction is widely used with many different implementations. 43,49,50 In general, any modulation cf. an equilateral polygon or Platonic solid inside the Poincaré sphere is optimal with respect to noise propagation to the (fractional) Stokes parameters.…”

We report the main conclusions from an interactive, multidisciplinary workshop on "Polarimetric Techniques and Technology", held on March 24-28 2014 at the Lorentz Center in Leiden, the Netherlands. The workshop brought together polarimetrists from different research fields. Participants had backgrounds ranging from academia to industrial R&D. Here we provide an overview of polarimetric instrumentation in the optical regime geared towards a wide range of applications: atmospheric remote sensing, target detection, astronomy, biomedical applications, etc. We identify common approaches and challenges. We list novel polarimetric techniques and polarization technologies that enable promising new solutions. We conclude with recommendations to the polarimetric community at large on joint efforts for exchanging expertise.

“…The use of liquid crystal polymers and dichroic dyes has allowed a full Stokes polarimeter [10], [49]. These sensors are capable of capturing polarization information at video frame rates, and their compact realization has allowed them to pertain to remote-sensing applications, such as underwater imaging [21].…”

In this paper, we present recent work on bioinspired polarization imaging sensors and their applications in biomedicine. In particular, we focus on three different aspects of these sensors. First, we describe the electro–optical challenges in realizing a bioinspired polarization imager, and in particular, we provide a detailed description of a recent low-power complementary metal–oxide–semiconductor (CMOS) polarization imager. Second, we focus on signal processing algorithms tailored for this new class of bioinspired polarization imaging sensors, such as calibration and interpolation. Third, the emergence of these sensors has enabled rapid progress in characterizing polarization signals and environmental parameters in nature, as well as several biomedical areas, such as label-free optical neural recording, dynamic tissue strength analysis, and early diagnosis of flat cancerous lesions in a murine colorectal tumor model. We highlight results obtained from these three areas and discuss future applications for these sensors.
