综 述:我想不少人认为电子式显示器是航空领域里的一项崭新的革新。其实,最初的电子式显示器就是早期的雷达显示器,曾在二次大战期间就使用了。令人惊讶的是,平视显示器(HUD)同样也在二次大战中使用过。不过当时的HUD是电子机械式的,而且在显示信息量方面受到极大限制。 首先人们要问:什么是HUD?简单的回答是,HUD是在驾驶员观察飞机前方外界的同时能给他提供信息的一种装置,信息显示在驾驶员正常视场内无限远处。
Summary: I think many people think that the electronic display is a brand new innovation in the aviation field. In fact, the original electronic display was an early radar display that was used during World War II. Surprisingly, the head-up display (HUD) was also used in World War II. However, the HUD was electromechanical at that time and was greatly limited in terms of the amount of information displayed. First of all people have to ask: What is HUD? The simple answer is that the HUD is a device that gives the driver information while watching the outside of the aircraft in front of him. The information is displayed at infinity in the driver’s normal field of view.
