Abstract:

A boresighting system including an optically pumped target member for correlating the boresight between a plurality of components such as a laser rangefinder/designator (LRF/D), a thermal imager such as a Forward Looking Infrared (FLIR) device, and a video system. The laser rangefinder is used as a reference with which to align the thermal imager and the video system. The target member and a visible source generator of the boresighting system provide multispectral capability without using any driving electronics. Both the target member and the visible source generator are located at the geometric focus of collimating optics used with the system, and, since, by definition, the geometric focus is equivalent to infinity, a point souce of radiation by the optically pumped target and the visible light generated by the visible source generator will appear to be extended sources from infinity.
