    • A method and apparatus is described for boresighting the sighting systems ed with a 1.06 micrometer designator laser. The method enables boresighting visual direct view optics, TV, and forward looking infrared (FLIR) sights with respect to the laser itself, without the use of external targets. The laser beam is focused onto a refractory target in the boresight device, creating very briefly an incandescent hot spot which can be "seen" by all three sensors. The radiation from this hot spot is collimated by the boresight device optics and projected back into the sights exactly anti-parallel to the laser beam. By aligning the sight reticles with this hot spot, all three types of sights are aligned relative to the laser. Since the hot flash created by the laser energy is of such short duration, the alignment can be accomplished in flight where relative motion exists between the laser designator system and the boresight module. The apparatus disclosed includes a CO.sub.2 laser alignment fixture and a reflective collimator with a phosphor thermal imaging disk for precision alignment of the laser input and FLIR output lines of sight of the boresight module.
    • 描述了用于对使用1.06微米指示器激光器的瞄准系统进行瞄准的方法和装置。 该方法可以在不使用外部目标的情况下使视觉直观观察光学,电视和前瞻性红外(FLIR)视野相对于激光本身。 激光束聚焦到视轴装置中的耐火材料目标上,非常简单地产生可被所有三个传感器“看到”的白炽热点。 来自该热点的辐射由视轴装置光学器件准直,并且投射回到与激光束完全反平行的视线。 通过将瞄准具与该热点对准,所有三种类型的瞄准镜都相对于激光器对准。 由于激光能量产生的热闪光具有如此短的持续时间,所以可以在飞行中实现对准,其中在激光指示系统和视轴模块之间存在相对运动。 所公开的装置包括CO 2激光对准夹具和具有磷光体热成像盘的反射准直器,用于激光输入和视轴模块的FLIR输出视线的精确对准。
