In order to raise the precision of the measurement and positioning, we adopted the laser encoder to serve as the feedback system, which can effectively slash the environmental disturbance.

碩士 === 淡江大學 === 機械與機電工程學系碩士班 === 99 === The positioning technique are widely used in various fields. Its positioning ca-pability of the stage usually influences the performance of the instruments or machines. The positioning capability of the stage, however, strongly depends on the displacement sensing technique. In order to raise the precision of the measurement and positioning, we adopted the laser encoder to serve as the feedback system, which can effectively slash the environmental disturbance. We integrated it and the actua-tor to control the positioning stage.
In this study, we integrated the laser encoder, which was developed by our labor-atory, and the nanopositioning stage to construct a new positioner.
