全息照相技术的应用与发展

菜单

摘要：近些年3D技术发展迅速，本文将对激光全息照相技术进行一番研究。针对普通照相技术只能实现二维拍照等不足，本文比较了激光全息照相与普通照相之间的区别，具体阐述了通过波前记录和波前再现两步来实现激光全息照相，利用波的干涉原理将物体振幅信息和相位信息记录下来，再通过光的衍射将记录信息还原出原物体，从而实现三维立体成像。在实验中，整个光学系统对精密度要求极高，所以实验中也要注意相关细节问题。激光全息不仅能够实现三维成像，而且记录信息易于保存、便于存储。在全息存贮、全息测量、全息显示等方面有长足的发展和广阔的前景。59379

Abstract: In recent years, the rapid development of 3D technology, this paper will be a laser holography technology for a lot of research. For ordinary photography technology can only achieve two-dimensional photographs and other problems, this paper compares the difference between the laser holography and the common picture, specifically elaborated the by wave front recording and wave front reproduction two step is to realize the laser holography and object amplitude information and phase information recorded down by using the principle of wave interference, again through the diffraction of light will record information to restore the original object, so as to realize the three-dimensional imaging. In the experiment, the entire optical system has a high requirement for the precision, so the experiment should pay attention to the details of the problem. Laser holography can not only achieve three-dimensional imaging, but also easy to save the record information, easy to store. In holographic storage, holographic measurement, holographic display, and so on, there are considerable development and broad prospects.

近些年，3D技术一次次的出现在我们的眼前，不管是春节联欢晚会的直播现场浮现的三维立体的红灯笼，还是电影院里Imax影厅里身临其境的三维电影、大型车展的3D视频。我们在3D技术面前一次次被折服被震撼的同时，不禁思考3D效果到底怎么来的呢？如何才能让3D技术走进百姓生活中去？而不单单只是出现在高端领域。
