本文提出一种三维漫射体的多重像一步彩虹全息方法。该法是在一步彩虹全息图的记录光路中加一光栅,使物光通过光栅衍射后经透镜成像在干板处,而得到多重像彩虹全息图。
This paper presents a multi-image one-step rainbow holography method for three-dimensional diffusers. The method is to add a grating in the recording optical path of the rainbow hologram in one step, so that the object light is diffracted by the grating and then is imaged on the dry plate by the lens to obtain a multi-image rainbow hologram.
