ABSTRACT:
An optical system and method for positioning a first object with respect to a second object, such as a refueling aircraft and an unmanned air vehicle are provided with the system, including a pattern of reflectors, an optical receiver, an optical transmitter, and a processor. The method and system permit processing two dimensional images of reflected signals and ranging of the reflector to the transmitter. An optical transceiver may also be used instead of a discrete receiver and transmitter. The reflector may include a pattern of peripheral retroreflectors and limit-angle incident retroreflectors that only reflect light incident upon the retroreflector within a predefined range of incident angles.
