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.
