ABSTRACT:
A optical fiber polarimeter (10) includes a plurality of polarizing optical fibers (14) each having a different orientation with respect to a common reference line. A charge-coupled device having an array of pixels (32) is adapted to receive the light from the optical fibers (14) and generate a signal relating to the intensity of the light impinging on each pixel to a signal processor (18) that also orders the signals according to the orientation thereof and thereby provides a polarization phase versus intensity signal output.
