Abstract

This paper introduces the principle of a new optical displacement sensor which is characterized by its ability to measure over long-range (millimetric) with sub-micrometric resolution the linear displacement of an actuator performing a helical movement. In this work, geometrical modeling of a sensor using conical grating is proposed. The sensor sizing is explained in order to reach optimal performances and its fabrication is demonstrated.
