Abstract

In this paper, the principle to generate the moving coordinate in time grating displacement sensor is analyzed. In order to simplify the structure of the time grating sensor and make its manufacture more easily, its fluctuation equation is analyzed and the relation and distinction between electric traveling wave and magnetic traveling wave are discussed. Then a new method to generate traveling wave is proposed based on these discussions. The method is employed with its corresponding mechanical structure to form a new type time grating sensor. Experimental results show that the sensor can generate correct signal and the method is feasible. Thus the traditional electrical machinery method can be replaced by a new method to generate the moving magnetic field. This new method can simplify the manufacture process greatly.
