研究设计了一种利用公共多媒体的光场调制相位成像实验教学系统，系统由辅助照明和图像记录两部分组成，其中的

辅助照明部分可由教室的公共多媒体投影仪实现，利用该教学系统可直接在课堂上现场演示操作过程.系统中采用了四步相移

与傅里叶频谱分析两种不同的相位解调算法实现三维像的数字化重构，并且针对于两种算法编写了软件操作界面，软件演示了

算法过程并对原理做出解释，从而更易于学生对光场调制相位成像原理的理解.

An optical field modulation phase imaging experimental teaching system using public multimedia is

developed.The system is composed of auxiliary lighting and image recording.The auxiliary lighting part can be implemented

by the classroom's public multimedia projector.The teaching system can be used to live demonstrations in

the classroom directly.The system uses two different phase demodulation algorithms———four-step phase -shifting

　　and Fourier spectrum analysis methods to realize numerical reconstruction of three-dimensional image，and a software

　　operation interface is written for the two algorithms.The software demonstrates the algorithm process and explained

　　the principle，which makes it easier for students to understand the principle of optical field modulation phase

　　imaging.

Key words： optical field modulation; three-dimensional imaging; phase demodulation; media instruction
