摘要
本文从彩虹全息固有的线全息图出发,不采用传统狭缝像的概念来分析彩虹全息的成像机理.论述了线全息图的宽度与再现像最小分辨距离及体视极限的关系;讨论了几种典型彩虹全息术中线全息图的特征及其对再现象的影响,提出并实现了不通过狭缝实像来观察再现像的新方法.
Based on the inherent line-element hologram of rainbow holography, this paper presents the illustration of the imaging mechanism of rainbow holography by no means of the traditional concept of slit images. The relationship between the width of line-element hologram and the minimum resolved distance as well as the stereo limit of the reconstructed image are discussed in detail. Characteristics of the line-element holograms and their effects on several typical rainbow holograms are illustrated and a new approach of observing the reconstructed image without the real slit image is proposed.
