为了实现头盔显示系统的功能, 在模拟器开发中, 采用体积小、质量轻的彩色微型有机发光显示器做图像源, 具有较高的亮度和分辨率; 通过构建双凸透镜和半透明平面镜组成的光学系统, 实现透视型、视准式显示, 满足了头盔显示的要求; 采用双摄像机和双红外辐射器图形的测量装置, 通过软件采集处理解算头盔位置, 使得位置测量范围大, 而且头盔附加质量小。应用结果表明, 模拟器通用性好, 功能和各项性能达到设计要求。该设计方案可为车载、舰载和机载头盔显示系统模拟器的研制提供借鉴。

In order to implement the function of a helmet display system, a small size and light weight color micro organic light emitting display (OLED) is used as image source in the simulator, which has higher brightness and resolution. The optical system is composed by double convex lens and translucent plane mirror, in which can satisfy the needs of helmet display by perspective and collimation display. The measuring equipment contains double cameras and double infrared radiators, meanwhile the helmet position is obtained by software collecting and processing, which can gain big position measurement range and small helmet added weight. The application results show that the simulator has good versatility and the functions and technical indexes reach the design requirements. The design can provide references for vehicle-mounted, ship-based and airborne helmet display system simulators.
