Abstract

We carry out a technological examination for improving the positional detection accuracy of position tracking. In this paper, we focus on positional detection technology that uses a scale in which slits are carved at a certain constant period. We develop phase modulation signal generation technology that removes a signal of two frequencies of a one-signal detection track. We report on the detection principle and the results of the principle verification experiment.
