摘要
本文提出一种合成狭缝可移动的彩虹全息术.若三维漫射体在(Xo,Yo)平面内平移照明物体的单色平面波处于(Xo,Zo)平面内则在透镜后你面上出现调制物光波复振幅分布的sine函数,其中心位置决定于物体平移的方向和照明物体的单色平面波在Xo方向的空间频率,从而实现合成狭缝可移动的彩虹全息术。
Rainbow holography with movable synthesized slitlike is presented in this paper. Diffuse three-dimensional objects are translated uniformly on Xo-Yo plane. The propagation direction of the coherent plane wave illuminating the objects is situated on Xo-Zo plane. As a result of this process, a sinc function madulating the complex amplitude distribution of the object is presented on the back focal plane of lens. The synthesized slitlike is formed. The central position of tile synthesized slitlike depend oil both tile direction of the object motion and spatial frequency of illuminating wave in Xo direction. Therefore Rainbow holography with movable synthesized slitlike is realized.
