| Summary: | 碩士 === 中華大學 === 機械與航太工程研究所 === 91 === Sinusoidal encoder and laser interferometer are frequently used methods for nanometer position control. We have constructed a high resolution subdividing electronics module to the sinusoidal encoder output of positioning motor. This module can be used as a counter for linear and angular measurements. It can subdivides the periods of the sinusoidal encoder signals up to 1600 times. The whole module is ideal for applications requiring high resolution encoder and fast data acquisition with phase tolerance. The design, experimental test, and standard deviation evaluation results have proved this module is suitable for high resolution nanometer measurement and positioning.
