摘要
介绍全息术在光学实验教学中的作用和数字全息及相移数字全息的发展.给出最近出现的广义相移数字全息的相移值抽取和物光再现的原理和公式.设计了适用于普通光学实验室的相移数字全息成像装置,从而将其引入本科实验教学.用反射物体进行光学实验,对文中设计的成像方法的可行性与有效性进行了验证.
The effect of holography on optical experimental teaching and the development of digital holography and phase-shifting digital holography are introduced.The principle and formulae of phase shifts extraction and objective reconstruction for generalized phase-shifting digital holography are given.The phase-shifting digital holography imaging setup is designed to use in ordinary optical experimental laboratory,introduced to undergraduate experimental teaching.Experimental research is carried out by using reflecting object to demonstrate the availability and effectiveness of this imaging method here.
