A polarization diversity detector includes at least one optical fiber having a first end for receiving a beam of light and a second end for transmitting the beam of light. A collimator receives the beam of the light from the optical fiber and outputs a collimated beam. A polarization diversity element includes a birefringent material which is positioned for receiving the collimated beam and resolving the collimated beam into a first beam having a first polarization and a second beam having a second polarization different from the first polarization. The first beam and second beam are angled relative to one another. At least one photodetector array pair includes a first photodetector array positioned to receive the first beam and a second photodetector array positioned to receive the second beam.
