发明名称 OPTICAL DEFLECTOR, OPTICAL SCANNER, IMAGE FORMING APPARATUS, IMAGE PROJECTING DEVICE, HEAD-UP DISPLAY, AND LASER RADAR
摘要 PROBLEM TO BE SOLVED: To provide an optical deflector that can ensure plane accuracy of a mirror part even at a high drive frequency to contribute to improvement of image quality.SOLUTION: The length of a drive beam and the amount of offset of a torsion bar with respect to the center of a mirror part are changed to determine a minimum point of a dynamic surface deformation of an optical reflection surface of the mirror part, and the position of the rotation center of the mirror part is determined with the center of the mirror part corresponding to the minimum point as the original point. An optical deflector is designed to have the determined rotation center.SELECTED DRAWING: Figure 7
