Abstract:
1. An optical deflection device comprising: a substrate; a plurality of regulating members respectively provided at a plurality of edge portions on an upper surface of the substrate, and respectively including upper portions including stoppers; a fulcrum member provided on the upper surface of the substrate, and including a top portion serving as an electrode configured to establish a potential thereof; a plate member movably placed in a space formed by the substrate, the fulcrum member, and the stoppers, the plate member comprising: a plurality of electrodes provided on the upper surface of the substrate to be approximately opposite to the conductive layer of the plate member and to surround the fulcrum member, wherein, when at least a part of the plurality of electrodes are fixed to predetermined potentials and a potential of the fulcrum member is changed, the plate member tilts and displaces around the fulcrum member due to electrostatic attraction force, and a light incident in the light reflecting region in a first direction is deflected and reflected in a second direction different from the first direction.
