To boresight the laser of a laser designator system to the null point of an automatic television tracker, by selectively causing the laser beam to be retroreflected to the video sensor of the system, which interfaces with a television tracker. The tracker locks onto the retroreflected laser spot, with the tracker error signals, in a feedback control loop, being used to control the video sensor raster bias to center the sensor sweeps about the laser spot, thereby nulling the tracker error signals and achieving boresight with the laser automatically.

In a laser designator system including a laser source, an imaging subsystem utilizing a sensor having a raster and a photosensitive surface, a tracker connected to receive information from said sensor and serving to generate error signals, and optical components for directing an output beam of energy from said laser source through an outlet port and for directing scene radiance entering through the outlet port to said photosensitive surface of said sensor, means for redirecting the output beam of energy from said laser source such that at least a portion of said energy falls upon the photosensitive surface of said sensor, means responsive to any misalignment of said sensor relative to said laser beam for generating signals indicative of said misalignment, and means responsive to said signals indicating misalignment for causing the center of the sensor raster to coincide with the laser output beam.
