  • Publication number: 20170227761
    Abstract: An image display apparatus includes a light source device including a light source unit; a scanning optical system including an image forming unit on which an intermediate image is formed by light from the light source unit; and a virtual image optical system configured to guide light of the intermediate image by using a reflecting mirror and a curved transmissive reflection member. The scanning optical system includes an optical scanning unit configured to scan the light from the light source unit in a main scanning direction and a sub-scanning direction of the image forming unit. The image forming unit is a transmissive member curved with a convex surface toward the reflecting mirror.

  • Publication number: 20170154558
    Abstract: An image display apparatus and a vehicle provided with the image display apparatus. The image display apparatus includes a light source unit to emit a laser beam, an optical deflector to deflect the laser beam two-dimensionally, and an intermediate image generator to perform two-dimensional scanning twice in a main scanning direction and a sub-scanning direction with the laser beam deflected by the optical deflector to generate an intermediate image of one frame, where the laser beam deflected by the optical deflector draws two scanning lines. In the image display apparatus, the two scanning lines have two different phases for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively. In the image display apparatus, the two scanning lines have two different starting points for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.

  • Publication number: 20160116735
    Abstract: An image display device includes an image forming unit configured to emit light forming an image; and a concave mirror configured to reflect the light emitted from the image forming unit toward a transparent reflecting member. The image forming unit includes a transparent member on which the image is formed or which forms the image, the transparent member being curved bulging toward the concave mirror.
