Abstract
A laser beam rider 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 x and y scan lasers, a synchronization laser, a scanning means for the x and y scan lasers, a first beamsplitter for directing the x and y scan laser beams through a zoom lens for focusing approximately at the missile's range, a second beamsplitter for focusing a portion of the x and y scan laser beams to a third beamsplitter for reflecting the portion of the x and y scan laser beams through a telescope sight to the reticle of the sight, reflecting means on the center of the sight reticle to reflect the portion of the x and y scan laser beams to a fourth beamsplitter, a light detector responsive to the reflected light for producing an electrical signal, when the x and y scan laser beams cross the line of sight to target for a signal processor, to trigger the synchronization laser. The signal processor can compute a delay in activating the synchronization beam to compensate for gravity, target m…
