Abstract:
A combined ranging/scanning system, comprising:a ranging transmit source aligned with a retardation plate on a beam path to transmit an outbound ranging beam of light; a scanning transmit source aligned with the ranging transmit source to transmit an outbound scanning beam of light; a lens aligned on the beam path to allow the outbound beam to pass through the retardation plate and through the lens; a receiver aligned on the beam path to receive an inbound ranging beam and an inbound scanning beam, the inbound ranging beam and the inbound scanning beam being reflected from an object; at least one scanning optic aligned on the beam path with the lens, wherein the lens and the scanning optic simultaneously process the outbound ranging beam, the outbound scanning beam, the inbound ranging beam and the inbound scanning beam; and a first selector aligned with the receiver to differentiate beam, the outbound ranging beam, the outbound scanning beam, the inbound ranging beam and the inbound scanning beam.
