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 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.

Abstract: Provided is an optical scanner including: a mirror driving unit which drives a scanning mirror which reflects light from a light source based on a drive signal; an optical sensor which detects scanning light entering first and second detection positions set on both sides of a range of the maximum scan angle within the range; and a calibrating unit which calibrates the intensity of the drive signal based on the time point at which the detection is performed and the frequency and intensity of the drive signal.
