Abstract
A laser beamrider guidance system having an improved launcher based laser transmitter subsystem for illuminating a laser beam receiver subsystem on-board a moving carrier is disclosed. The improved launcher based laser transmitter subsystem includes a boresight compensation mechanism having L-shaped x and y scan diode lasers and a synchronization laser, a rotating scanning means for producing two rotations of the laser beam images for each rotation of the scanning means, a zoom lens in the optical path of the x and y scan rotating lasers for focusing the laser beams within the maximum target range, a first beamsplitter for reflecting a portion of the x and y scan laser beams to a telescopic sight mechanism adapted to determine when the x and y scan laser beams cross the line of sight to target and activate a signal for activating the synchronization laser beam.
