Abstract: Systems capable of acquiring polarimetry data using a single camera with or without a polarizing filter. When a polarizing filter is used, the data acquisition method comprises: (1) maneuvering the aircraft (or other vehicle) to orient the polarizing filter (and camera) in various directions when images are captured, (2) registering the various images to each other, and (3) computing polarimetry values (such as the Stokes parameters) for points of interest in the images. When a polarizing filter is not used, the data acquisition method comprises maneuvering the aircraft (or other vehicle) to orient the camera in various directions when images are captured and then performing the same operations (2) and (3). These methods measure the amount of polarization in a given scene by taking multiple camera images at different angles.

Abstract: A system, apparatus and method for analysis of a specimen using ellipsometric analysis. Polarization distortions caused by the propagation of polarized light within a substrate upon which a specimen is located are reduced by directing light at selected polarizations at the substrate alone and the specimen on the substrate. Image data is collected for each of the selected polarizations and processed to remove errors due to birefringence. Fourier transform processing is used to obtain polarization phase data for correcting polarization caused by any birefringence in the substrate, and optionally amplitude data.
