Study on Technique of Measuring Single Grating Incremental Angle
This paper discusses a new method of measuring incremental angle, which uses an arranged matrix of a narrow slit photoelectric cell according to certain logic phase combination replacing the fixed grating in the grating pair. The measuring operation can be accomplished by the coordination to replace between the coder disk and the arranged matrix of the narrow slit photoelectric cell. Thus, there is no need of considering the gap between the slit and the coder disk. The sensibility of the incremental photoelectric encoder to the vibration and the precision requirements of the spars are deduced. Thus the contrast degree of the Moors fringes is enhanced, the subdivision precision is increased and finally the measuring precision and the Stability are all increased.
