  • Two-dimensional optical scanning mirror device, manufacturing method for same, two-dimensional optical scanner and image projector
    Patent number: 11307407
    Abstract: A two-dimensional optical scanning mirror device, a manufacturing method for the same, a two-dimensional optical scanning device and an image projector. A two-dimensional optical scanning mirror device includes a substrate, a movable mirror portion supported on the substrate in such a manner that two-dimension optical scanning is possible, a hard magnetic thin film provided in the movable mirror portion and a magnetic field generator that includes at least an alternating magnetic field generator for driving the movable mirror portion, where the hard magnetic thin film has a magnetization direction in a direction of a film plane, and the ratio of the magnetic field generated by the magnetic field generator relative to the coercive force of the hard magnetic thin film is 0.2 or lower.
    Type: Grant
    Filed: April 27, 2020
    Date of Patent: April 19, 2022
    Assignee: NATIONAL UNIVERSITY CORPORATION UNIVERSITY OF FUKUI
