光纤光束变换器在大视角彩虹全息中的应用

Making Large Viewing Angle Rainbow Hologram Using a Fibre-bundle Beam Translator

用光纤制成的光束变换元件代替大孔径透镜和狭缝拍摄彩虹全息图．大大提高了全息图的视角．而且方法简单。介绍了用光纤光束变换器拍摄大视角彩虹全息图的原理、方法．并进行了实验验证，得到了较为满意的效果。

We use a new optical element──fibre-bundle beam translator in place of largeaperture lens and slits to make rainbow hologum for raising the viewing angle.This paperinttoduces the principle of the beam translator and also gives the experimental results.
