1955年首次提出平视显示器预研方案,1958年设计出世界上第一套军用飞机平视显示器。经过20多年的不断改进,平视显示器已有很大发展。现在的平视显示器已不单纯是光学技术和电子显示技术的结合,而是数字技术、电视技术、衍射光学等多种技术的结合。使其成为现代化飞机上不可缺少的先进电子仪表。本文着重介绍平视显示器光学系统的改革。 (一)概况平视显示器是在反射式光学瞄准具和雷达瞄准具的基础上发展而来的。它的光学系统仍然保留了反射式光学瞄准具的基本光路,只是
First proposed in 1955 HUD pre-research program, in 1958 designed the world’s first military aircraft head-up display. After 20 years of continuous improvement, head-up display has been greatly developed. Today’s head-up display is no longer simply a combination of optical technology and electronic display technology, but the combination of digital technology, television technology, diffractive optics and other technologies. Making it an indispensable advanced electronic instrument on modern aircraft. This article focuses on the reform of the HUD optical system. (A) Overview Head-up displays are based on reflective optical sights and radar sights. Its optical system still retains the basic optical path of a reflective optical sight, just
