大视角彩虹全息新设计

New Design for Making Rainbow Hologram with Large Viewing Angle

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.本文介绍了用光纤光束变换器的摄大视角彩虹全息图的原理、方法,并进行了实验验证,收到了较为满意的效果.

We use a new optical element-fibre-optic beam translator in place of large aperture lens and slits tomake rainbow hologram for raising viewing angle. This paper introduce the work principle of the beam translator and give experimental results.
