This method adopts a collimator tube that can be measured as a target fixed to the test table  and the target corresponds to the angular position of the test table. In the process of the table rotating  the camera will to keep track of the objective at a high speed. Due to the high sampling frequency of the high-speed camera  instantaneous angular rate of test table can be measured. With pixel subdivision technology  its measuring accuracy can be up to 0.02 pixels. We use this methods measured a low-speed test table's angular rate and analyzed the data. The error analysis shows when the rate of the test table is 0.20/s  the accuracy of the method can achieve 0.0220%. 2009 IEEE.
