Real time complete Stokes polarimetric imager based on a linear polarizer array camera for tissue polarimetric imaging

Tissue polarimetric imaging measures Mueller matrices of tissues or Stokes vectors of the emergent light from tissues (normally using incidence with a fixed polarization state) over a field of view, and has demonstrated utility in a number of surgical and diagnostic applications. Here we introduce a compact complete Stokes polarimetric imager that can work for multiple wavelength bands with a f...

Visible-regime polarimetric imager: a fully polarimetric, real-time imaging system.

A fully polarimetric optical camera system has been constructed to obtain polarimetric information simultaneously from four synchronized charge-coupled device imagers at video frame rates of 60 Hz and a resolution of 640 x 480 pixels. The imagers view the same scene along the same optical axis by means of a four-way beam-splitting prism similar to ones used for multiple-imager, common-aperture ...

Rapid time-gated polarimetric Stokes imaging using photoelastic modulators.

We report a rapid time-gated full Stokes imaging approach without mechanically moving parts, which is well-suited for biomedical applications, using two photoelastic modulators (PEMs). A charge-coupled device (CCD) with microsecond time-gating capability was used to acquire the images. To synchronize the CCD with the PEMs, thus gaining signal-to-noise ratio advantage, a field programmable gate ...

Polarimetric Effects in Non-polarimetric Imaging

Radiative transfer is commonly modeled as the propagation of unpolarized radiation. More accurate approaches utilizing polarimetric quantities are usually only applied to sensors that purposefully discriminate polarimetric information. In this paper, we examine the effect on fidelity of utilizing polarimetric radiative transfer modeling for non-polarimetric sensors. We show that if the primary ...
