Optically controlled device, method of controlling the optically controlled device, spatial light modulator, and projector

摘要

An optically controlled device includes a transparent electrode (202), a conductivity variable portion (203), a driving electrode (204), a movable unit (108), and a support portion (206). A method of controlling the optically controlled device includes inputting a control light into the transparent electrode, applying a voltage between the transparent electrode and the movable unit modulating either the intensity of the control light or the voltage according to an input signal, and moving the movable unit to a predetermined position by generating a force proportional to the voltage between the driving electrode and the movable unit based on a change of electrical conductivity of the conductivity variable portion. <IMAGE>
