一 前言 最近在各地展出的可用太阳光、电灯光等白光再现的彩色全息图和多重全息图十分引人注目,关心这种全息照相术的人日益增多。全息照相术发明已有30年的历史,这种技术在干涉计量、非破坏性检查等方面已得到部分应用。此外,在使装置重量轻、体积小的光学元件以及显示器方面的应用越来越多,因为显示器可充分利用全息照相的特性:三维图象记录和“再现”。 利普曼全息照相从原理上来说也是可用白光再现的全息图,1962年由苏联的特尼休克提出。顾名思义,是以利普曼的天然色照相原理为基础。但由于记录的干涉条纹的间隔非常窄,在最初阶段再现像较暗,制作也困难,故并不引人注目。后来对记录材料和
A foreword Recently displayed in various places available sunlight, light and other white light reproduction of color hologram and multiple holograms is very compelling, increasing concern about this holographic people. Holographic invention has been 30 years of history, this technology has been partially applied in interferometry, non-destructive examination and so on. In addition, there is an increasing use of optical devices and displays that make the device lightweight, small in size, as displays can take full advantage of holographic features: three-dimensional image recording and “reproduction.” Lippmann holography is, in principle, also a hologram that can be reproduced in white light, and was put forward by the Soviet Union in 1962 by Tenet shock. As the name suggests, is based on Lipman’s natural color photographic principles. However, since the recorded interference fringes are very narrowly spaced and appear darker in the first stage and difficult to fabricate, they are not noticeable. Later on the record material and
