2 Outline Polarimetry Background Stokes vector Types of Polarimeters Micro-polarizer Camera Data Processing Application Examples Passive Illumination Active Illumination Advanced Interferometric Applications 2
3 Polarimetry Background Stokes Vector -George Gabriel Stokes in 1852 Total Intensity Horizontal /Vertical ± 45 RHC/LHC The Stokes vector can fully describe any polarization state, both partial and purely polarized 3
4 Conventions The Stokes vector is defined relative to the following six flux measurements P performed with ideal polarizers in front of a radiometer (Shurcliff, 1962) : P H horizontal linear polarizer (0 ) P V vertical linear polarizer (90 ) P linear polarizer P linear polarizer P CR right circular polarizer P CL left circular polarizer 4
5 Mueller Matrix Output System Xfer Input 5
6 Types of Imaging Polarimeters Division of Time (rotating elements) Can get all parameters Takes time - Not for dynamic scenes Division of Amplitude (multiple cameras) Bulky, expensive, registration, calibration Division of Aperture (one sensor multi images) Registration issues, distortion, loss of resolution Division of Focal Plane (DoFP) Resolution loss, xtalk J.

22 Active Illumination If illumination is controlled: Assume all light is polarized (random = 0) Use Mueller matrix calculation to solve for change, e.g. retardation, birefringence, pol. angle. Error sources External: o Ambient light, multi-path Internal: o Bandwidth of source, Polarization of source o Detector (linearity, gain, offset, noise, blooming, smear) o Mask (uniformity, contrast) Requires Calibration 22
