ABSTRACT:
An actuator having an asymmetric rigid structure for changing an optical beam path. The actuator has a base plate installed in a cover, first electrodes installed on an upper surface of the base plate by evaporation, a driving electrode disposed between the first electrodes, a pair of support plates each installed on a respective one of the first electrodes for receiving a voltage from the first electrodes, a reflecting plate disposed between the pair of support plates for reflecting an incident beam emitted from a beam source, and asymmetric members connected to the reflecting plate for adjusting an incident path of the incident beam and an inclination angle of a reflection beam with respect to the incident beam. The actuator can easily adjust the incident path of the incident beam and an inclination angle of the reflection beam with respect to the incident beam by asymmetrically inclining the reflecting plate. The actuator has only one driving electrode so that the driving conduit thereof is simply formed and reliable operation thereof is be attained.
