中文摘要	The modulation of photon polarization by liquid crystal variable retarder (LCVR) whose phase retardation can be controlled easily by its driving voltage is described. A spinning polarimeter is designed to calibrate the LCVR for 820 nm wavelength in situ. The driving voltages corresponding to 1/4 lambda , 3/4 lambda , 1/2 lambda and 1 lambda of LCVR are obtained, and the polarization of photon is modulated by changing the driving voltage via a computer. The theoretical analysis and experimental result are presented. The advantages of the proposed method are insensitivity to the incident photon direction, large wavelength range without mechanical movement, and real-time control.
