  • An angular velocity measurement system for rotary table using ring laser gyroscope and self-calibration angle encoder is designed, which enables the measurement and data acquisition of the angular position and angular velocity of rotary table in a single circumference range. A test platform is built using a self-calibrating angular encoder and a ring laser gyroscope to monitor the motion state of the rotary table, and the collected data are analyzed to obtain the angular position and angular velocity information. Through experiments at different speeds, a series of angular positions and angular velocity deviation curves and their Fourier transform analysis results in the single circumference range of the rotary table are obtained.
