美国休斯研究实验室研制成一种飞机驾驶员用的显示器,利用一种新的全息照相技术与激光偏转技术相结合,使视野显著加宽。 据称,这种新的技术是利用全息照相的波前透射特性形成一个光学元件,而不是记录三维景象。这种元件叫做“点源全息照片”,可以用来代替一般的透镜和反射镜。当它被一个参考光束照射时,产生一个光点而 The Hughes Research Laboratory in the United States developed a display for aircraft pilots that uses a new holographic technique combined with laser deflection technology to significantly broaden the field of view. Allegedly, this new technology is the use of holographic wavefront transmission characteristics of an optical element, rather than recording three-dimensional scene. This component is called “point source hologram” and can be used to replace general lenses and mirrors. When it is irradiated by a reference beam, a spot is generated
