ABSTRACT:
An optical target detector utilizes a star coupler to achieve automatic alignment of "pencil" laser beams. A number of "pencil" beams of laser light are deployed from the surface of a projectile in order to detect a target. The laser light is transmitted to the target and reflected back from the target to the optical target detector. The light tramsmitted, in the form of a number of "pencil" beams, and the light being reflected by the target are transmitted through a star coupler device in order to maintain alignment for the transmission of maximum light signal strength and simultaneously to minimize aerosol backscatter.
