Abstract

A novel method to measure the roll angle using a quarter wave plate and a Wollaston prism is presented in this paper. The setup and principle of the measurement system are introduced. According to the optical structure, the mathematical model was established by Jones matrix method. The output voltage from an optical detector located after the Wollaston prism can be used to determine the roll angle. Theoretical analysis and experimental results show that the sensitivity of roll measurement can reach arc-second. The chief advantages of the sensor are simply, stable and compact. This system can be applied to dynamic roll angle measurement. Experimental results have shown that the angular resolution is 0.04 arc-minute in a ±40 are-minute range.
