Several techniques are described for boresighting 1.06 pm designator lasers to visual, TV, and forward looking infrared (FLIR) sights. One concept can be used to boresight all three types of sights, even in flight with relative motion between the laser designator system and the boresight module. Special factory hardware incorporating a CO2 laser, a reflective beam expander telescope, and a phosphor thermal imaging disk was developed for precision alignment of the laser input and FLIR output lines of sight of the boresight module. The operation and effectiveness of the boresight module is illustrated by airborne sensor video imagery and missile firing test results.
