Dynamic Characteristic Analysis of Angle Measurement Based on Laser Gyro Goniometer
In order to make the dynamic angle measurement results reliable and credible,the dynamic char-acteristics of laser gyro goniometer need to be analyzed before dynamic angle measurement.In this paper,firstly,the laser gyro goniometer distribution is synchronously triggered with the turntable and the laser in-terferometer through the synchronous trigger device,and then the turntable simulates the pulse response mo-tion,step response motion and sinusoidal motion.Finally,the output data of the laser gyro goniometer and the turntable's circular grating and laser interferometer in different motion processes are compared and ana-lyzed.The results show that the laser gyro goniometer has good dynamic characteristics,and the dynamic angle measurement accuracy of the laser gyro goniometer at different frequencies is about 0.6″,which guar-antees the reliability of the dynamic angle measurement results of the laser gyro goniometer.
