摘要
头盔显示器可以给驾驶员提供武器瞄准和飞机姿态等信息,已成为现代军用飞机座舱显示系统的重要组成部分。在头盔显示器中加装夜视装置,使头盔显示器具有夜用功能是一项迫切的军事需求。分析了夜视镜的原理和作用,给出了夜视镜和头盔显示器综合的两种方法及国外典型的综合实例,对夜视镜与头盔显示器综合中的主要问题——分辨率与视场问题进行了深入研究。分析表明,对综合夜视头盔显示器的重要技术指标应该根据具体情况折衷考虑。
Helmet-mounted displays(HMD) has become an important part of the cockpit display system for military aircraft,which can supply information for weapon aiming and aircraft guidance.The integration of night vision system in HMDs to make the HMDs applicable during night time is an urgent military need.The working principle and function of night vision goggles(NVG) are analyzed,two primary methods for integrating HMDs with NVGs are presented with typical examples.The main problem existed in integrating NVGs in of HMDs,i.e.,the resolution and field of view,are studied.It is shown that the performance indexes of integrated HMD should be considered according to its application.
