A method for determining and displaying polarization profiles of points in
a scene from a single imaging detector array, which utilizes a filter
system comprised of a retarder, four linear polarizers, four lenses, a
color filter, camera lens and CCD video camera. Light from points in a
scene are transmitted through the system and exits with attenuated
intensities unique for each wavelength of the light. A narrowband color
filter selects the wavelength of interest. The four lenses in the system
produce four images of the scene, which are recorded as a single
CCD-image. The attenuated intensities in each of the four scene-images
are used to calculate the Stokes parameters for selected points in the
scene for the selected wavelength. A computer program separates the four
scene-images in the CCD-image, crops, registers them and calculates the
Stokes parameters for each point in the cropped scene.
