ABSTRACT:
A sensor testing apparatus which is capable of testing any sensor regardless of the type of polarization the sensor is sensitive to. The testing apparatus comprises a source conditioning apparatus to produce a beam of optical energy of a known polarization state. A polarization conditioning apparatus changes the polarization state of the optical energy beam to any desired polarization state. A transmit quadrant detector detects the polarization of the optical energy and the optical energy is directed to a sensor to be tested. The optical energy transmitted by the sensor is detected by a receive quadrant detector. The polarization state is displayed on the monitor of a computer by virtue of a computer interface with both quadrant detectors.
