Abstract
Boresighting apparatus includes a laser, a thermal target having an absorbent surface for receiving the laser beam and converting it to a heat spot of infrared radiation, and an optical device for receiving and optically displaying the heat spot. The thermal target is anisotropic, having a low thermal conductivity in the direction laterally of the surface and a high thermal conductivity in the direction perpendicular to the surface, so as to increase the duration of the heat spot with a minimum lateral spreading.
