In order to solve the problems existing in the photoelastic experiment of undergraduate experimental teaching, a video acquisition teaching software is developed based on USB industrial camera and three variable lens. The hardware installation of the video acquisition system is simple, just needs to connect industrial camera's USB interface to the computer's USB , then make the serial port of decoder connect to the serial port of computer, then the system can be used. The design of interactive

By using VB serial communication technology, the control of three variable lens' focal length, focus and aperture is completed. The acquisition system has been used in the experimental teaching, it successfully solves the problems that students are difficult to observe images and teachers are difficult to explain in the photoelastic demonstration experiments.
