Paper Abstract
To evaluate the angular velocity accuracy and uniformity among 0°~360° of a rotary table, two real-time angular position measuring systems were setup base on self-calibration angle encoder and ring-laser gyroscope (RLG) separately. The angular position acquisition triggered by programmable clock enabled angular velocity measurement with flexible angular interval, and realize the angular velocity calibration of the rotary table with required angular interval among full rotary circle. The calibration results obtained from self-calibration angle encoder and ring-laser gyroscope were identical and provided a series of detailed angular velocity deviation curves.The angular velocity deviation demonstrated periodic feature among 0°~360°. A series of comparisons were carried out, and then the relation between the angular velocity deviation and angular position deviation was analyzed on both of dimensional domain and Fourier domain.
