本文介绍全息相位共轭原理,提出了一种应用的实验方案.并指出它与非性线光学中光学相位共轭技术的不同以及它具有的优异特性.运用全息相位共扼技术作干涉计量,研制的仪器可以弥补经典干涉仪测量的不足.仪器采用中继光学系统可提高测量精 This paper introduces the principle of holographic phase conjugation and presents an experimental scheme of application. It also points out the difference between it and the optical phase conjugation in non-linear optics and its excellent characteristics. By using the holographic phase conjugation technique for interferometry, Developed instrument can make up for the lack of classical interferometer measurement instrument using relay optical system can improve the measurement of fine
