摘要
介绍了数字全息的基本概念和原理,以及在动态测量上的应用,分析了目前消除数字全息再现物体图像时零级光影响的常用方法,重点介绍了相移技术.为提高再现物体图像质量,还介绍了光学超分辨在数字全息中的应用.
The basic concept and principle of digital holography and its application measurement are presented. The methods of eliminating the zero-order diffraction light hologram in object reconstruction are introduced with emphasis on phase-shift technology raise the image quality of reconstruction object, the optical superresolution technology is in dynamic from digital In order to used.
