摘要:
An automatic testing illumination system has advantages of speed, quick calibration ability and therefore high accuracy over conventional illuminators. An spherical light source/concentrator exit port is rapidly and sequentially covered by at least one automated device for affecting the light leaving the exit port. Automation enables a very rapid sequencing of light onto a two or three dimensional array to cut the time for test and evaluation, and to permit very accurate calibration of the illuminator system.
摘要:
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.
