Polarization is one of the basic characteristics of light，which is widely used in the industrial production and the scientific research．Polarization of light is one of the important contents in the teaching of college physics experiment and physical optics．VirtualLab Fusion software is applied in the teaching process of the polarized light． Combined with the scientific research projects，the theories of the optical activity measurement and the generation of vector light field are analyzed，and their simulation experiments are carried out based on the VirtualLab Fusion．The simulation experiment is three-dimensional and intuitive，which is helpful for motivating students’study enthusiasm and improving students’innovative thinking and innovative

ability．This study can provide some beneficial reference for the teaching reform of college physics experiment and physical optics course．
