The basic principle of a dynamic goniometer based on fiber optic gyroscope was introduced. According to this principle, the model on uncertainty of angle measurement results was established and the simulation analysis on uncertainty of measurement results was performed. Furthermore, a series of repetitive experiments with this goniometer at different rotational velocities were carried out. Experiments results showed that they were consistent with the uncertainty got from the theoretical analysis when the confidence level was set to 95% and the evaluation model on uncertainty was effective.
