Combined range-finding, sighting and scanning system and method

摘要

An optical system is provided which combines range-finding (distance measurement), sighting (target acquisition) and scanning capabilities. This single beam system uses a polarization selector and a retardation plate to take advantage of the polarization properties of light from a transmit source and of light reflected to a receiver. The system further includes scanning optics for moving the optical beam of light in relation to object in order gather information from the object. Methods for using the system are also provided.
