Optical deflecting device, optical deflecting device array, method for driving the optical deflecting device and image projection display apparatus using the device |
摘要 |
An optical deflecting device includes a plate-like member having a light reflective area and a conductor layer. The plate-like member rotates with substantially the middle portion thereof made a fulcrum to change an inclination direction thereof and thereby a reflection direction of a light flux incident to the light reflective area is changed. A first electrode group and a second electrode group are arranged so as to oppose the conductor layer of the plate-like member, respectively, and to sandwich a position corresponding to a position of the fulcrum of the plate-like member. Each electrode group includes a control electrode controlling starting of the plate-like member and a drive electrode driving the plate-like member.
