Abstract： This paper proposes a high-speed measurement method of Mueler matrix based on an overdriving technique exerted ona liquid crystal variable retarder.First，a liquid crystal-based simulation model of the Mueller matrix measurement system is established，which helps to confirm the feasibilityofthe system.Next， anoverdrivingschemefor the liquidcrystalvariable retarder is introduced to shorten the polarization-state switching time.Finall，the Mueller matrices ofair，apolarizer，anda quarter-wave plate are measured experimentally.The results show that the generation frequency of six polarization states increases from 71Hz to 417Hz， and the measurement frequency of Mueller matrix increases from 10Hz to 60Hz representing approximately a sixfold improvement.Furthermore，the mean squared error （MSE）of the measurements is below 0.0oo4.The extinction ratio exceeds 750：1，and the ellipsometric error is below 1.06% .These results demonstrate that the overdriving method enables high-speed Mueler matrix measurements，thereby facilitating applications in real-time inspection fields such as dynamic polarization analysis，online quality inspection of optical components，and biomedical imaging.
