平视显示器的视差调校研究

平视显示器图像源上同一光点给出的瞄准线束的不平行性性称为平视显示器的视差，视差能引起视觉疲劳并带来瞄准误差，地对平视显示器视差产生的三种根源采取相应对策消除平视显示器视差，示数观测镜是用于光装工位的平视显示器视差调校设备，精确方便。双管同显示器视差检测仪选用两单筒凯涅尔型望远镜组装，效费比高。

Study on adjustment and correction of HUD parallax

Parallax of Head Up Display (HUD) refers to the unparallelism of aiming beams sent from the same light point on the imaging source of HUD. Parallax may cause visual fatigue and aiming inaccuracy. Therefore corresponding measures should be taken for three different sources of parallaxes. As an equipment for the adjustment and correction of HUD parallax, reading indicator is accurate and convenient. Binocular tester for HUD parallax mainly consists of two monocular telescopes, which has fairly high E/O ratio.
