ABSTRACT:
A device for receiving and reflecting light beams includes a central processing unit for analyzing a first portion of a received light beam, at least one reception unit for receiving the light beam and reflecting a second portion of the light beam, and an optical conductor disposed between each reception unit and the central processing unit for transmitting the first portion of the received beam to the central processing unit. An optical element is positioned between the reception unit and the optical conductor for converging the light transmitted through the conductor. The central processing unit may also include a directional scanner which will calculate the direction of travel of the incident light beam. The device may also include at least one light source which is adapted to emit an optical response signal. A retroreflector is provided within each reception unit and is adapted to reflect the second portion of the incident light beam in a direction parallel and opposite to the direction of the incident beam.
