Paper Abstract

In an angle calibration instrument and a generating machine of radial grating, the opto-electronic signal is generated by a novel fiber optic whole-circum sensor. The construction of the sensor is introduced, the principle to i prove the accuracy under partially coherent illumination is derived, and the experimental results are presented. Because of its excellent characteristic, the residual phase error (peak to peak) of moire signal is less than 0.03 sec. of arc., the accuracy of machine is increased about 30 times.
