Abstract: An eyeglass-type video display device includes a video generation device and an eyeglass body. The video generation device includes a MEMS optical deflector and a VCSEL mounted on the same substrate, and a planar mirror and a rotating mirror arranged above the substrate. Light emitted from an emission part is emitted obliquely upward from one longitudinal-direction end side of the substrate through the planar mirror, the rotating mirror, and a revolving mirror. The video generation device is attached to an arm of the eyeglass body such that the emission direction of the light becomes a direction that is obliquely forward with respect to an inner side surface of the arm.

Abstract: An optical scanning device includes a VCSEL and an emission unit mounted on the same substrate, and a bottom plate portion arranged on the lower side of the substrate. A columnar protruding portion has a tapered shape and is plastically deformable, and is fixed to the bottom plate portion. The columnar protruding portion has a distal end side inserted into a through hole portion of the substrate. At least one of an upper portion of the columnar protruding portion and the through hole portion is plastically deformed so that they are fitted to each other. A relative inclination angle between the substrate and the bottom plate portion is defined by a fitting angle between the through hole portion and the columnar protruding portion.

Abstract: An optical deflector driving method includes inputting an instruction to change at least one of a first driving signal corresponding to a first driving voltage and a second driving signal corresponding to a second driving voltage, the first driving voltage and the second driving voltage being applied to an actuator swinging a mirror portion of an optical deflector around a swing axis; determining, in a case where the instruction is input, a timing when a voltage of a driving signal to be changed out of the first driving signal and the second driving signal becomes minimum; and reflecting, in a case where it is determined that the timing when the voltage of the driving signal to be changed becomes minimum comes, the change on the driving signal to be changed.

Abstract: An optical scanning device includes a light source and a MEMS optical deflector mounted on the same substrate, at least one optical path generation mirror configured to generate an optical path which causes a light beam emitted from the light source to enter the MEMS optical deflector, and a lens arranged between the light source and the first optical path generation mirror. A shielding plate has an elliptical aperture and is attached to the optical path generation mirror. The light beam from the lens has a peripheral edge on a cross section thereof, which is cut by the elliptical aperture.

Abstract: An optical scanning device includes a standing plate part which has an inclined groove and a through hole at positions above a vertical cavity surface emitting laser (VCSEL) and a micro electro mechanical systems (MEMS) optical deflector, and which is fixed to a substrate. A plate-shaped mirror and a rotary mirror have one end portions thereof in the Y-axis direction supported by the inclined groove and the through hole, respectively. The through hole has the shape of a rotating body having an axis in the Y-axis direction as the centerline thereof.
