Abstract (en)

[origin: WO9610729A1] Optical transceiver apparatus for measuring angular misalignment between two bodies in elevation, azimuth and roll utilizes a light transmitter (40) coupled to a first body such as an aircraft fuselage reference and a light receiver (12) coupled to a second body such as an aircraft wing or pylon. The receiver has an elevation/azimuth (EL/AZ) channel and a roll channel sharing a common objective lens, wherein a beam splitter (45) splits the beam generated by the laser diode (10) between the two channels. In the EL/AZ channel lenses are used to focus light onto a position sensitive detector (PSD) (46), while in the roll channel, a Thompson beam-splitting prism (13') or other suitable optimal element divides the two planes of polarization which are then focused on light detectors (16).
