摘要
用双透镜记录三维漫射物体的一步彩虹全息图,此方法在曝光过程中只移动一个透镜就可以在观察的位置形成合成狭缝.两个透镜用一个短焦透镜以增加可视角和使狭缝变窄,同时也提高了分辨率和光能的利用率.
In this paper one -step rainbow holograpy that uses dual lens for recording a three -dimensional diffuse object is discussed. During the exposure process, only one of the lenses is moved so that a synthetic slit is formed at the observation position. Both of the lenses can have a shorter focal length, which has the effect of expanding the visual field and narrowing the synthetic slit. This method simplifies the experimental technique needed for synthetic - slit holography.
