  • Patent number: 4583852
    Abstract: A system for measuring the relative orientation between two objects. A transmitter/receiver assembly on one of the objects transmits a beam of monochromatic light to a Ronchi-type retro-grating disposed on the other object. The grating reflects the light back to one or more charge transfer device area arrays in the transmitter/receiver assembly which provides orientation data to a computer which determines relative pitch, yaw and roll between the two objects.
