摘要
简述了用于测试平视显示器和照相枪主要性能的火控校靶仪的功能需求、工作原理和设计方案,包括光学系统和机械结构。照相枪校靶镜的线视场达到了(35 36±0.5)mm;OB读数观测镜视场达到了24°,屈光度为+3°~-4°,水平调整和垂直调整均为180°;分划板的精度为1′,且中心交点的不同心度小于±0.01,刻线不直度不大于0.002;照相枪校平玻璃上的十字中心和平视显示器光环中心相重合的公差为±°3mil,平视显示器光环中心同靶板上的照相枪校准点的公差为20mm。
The functional requirements, operating principles, and design schemes, including optical systems and mechanical structures, of fire control target verifiers are briefed. The line field of view of the camera gun calibrator reaches 35.36±0.5 mm; the field of view of OB reading observation mirror reaches 24°, its diopter is +3°~-4°, and both horizontal and vertical adjustments are 180°; the accuracy of the graduation scale is 1', the eccentricity at the central intersection point is less than ±0.01, the nonstraightness of reticle is no more than 0.002, the tolerance for the coincidence of the cross center of the adjusting plane glass on the camera gun with the reticle center of the head-up display is ±03 micrometer, and the tolerance for the reticle center on the head-up display and the camera gun calibration point on the target board is 20 mm.
