Abstract

We proposed to manipulate the exit direction of laser beam precisely by controlling a thickness of a dielectric elastomer actuator. Because the deflection of the dielectric elastomer was activated by voltage, there is no mechanical movement in the system. Moreover, the direction is determined based on position instead of angle, so this application is valid for long distance. In our experiment, we confirmed that the light path was varied as the applied voltage increased from 0 to 7.1 kV. It is possible to be used in the field of general precise laser beam pointing applications, e.g. laser forming, light tweezers, and so on.
