ABSTRACT:
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.
