Abstract

this paper analyzes the characteristics of three typical angular displacement sensors, such as optical grating, inductosyns and time grating sensors, and a novel design method is presented. This method is based on the synthetic principle of electrical travelling wave. The precision of optical grating sensor is improved with the proposed method. Experiment results prove the valid of synthetic time-space orthogonal travelling wave, which realizes the transformation from the incremental sensors to absolute ones.
