    Abstract: An information display apparatus reflects light representing information off a projection target to display the information as a virtual image, and includes a projector, at least two image forming devices and a focus adjusting device. The projector projects the light representing information. The image forming devices, to which the light from the projector is projected, are on an optical path from the projector to the projection target. At least one of the image forming devices is at a distance from the projector different from that of other image forming devices. The focus adjusting device adjusts a focal length of one optical system on an optical path from the projector to each of the image forming devices such that the light from the projector is in focus at each of the image forming devices. An image of information on each of the image forming devices is reflected off the projection target.

    Abstract: A light guide member includes an incident portion, an emission portion, a reflection portion, and an inclined portion. An internal reflection angle inside the reflection portion and the emission portion is larger than an incident angle of an external light with respect to a first normal line that is a normal line of the emission portion. A first inclination angle that is an inclination angle of the incident portion with respect to the first normal line is smaller than the internal reflection angle. A height from the emission portion to a second side of the incident portion is larger than a distance between the emission portion and the reflection portion. A second inclination angle that is an inclination angle of the inclined portion with respect to the first normal line is smaller than the internal reflection angle.

    Abstract: A head-up display includes a concave mirror actuator that changes, based on external instructions, a reflection angle by which a concave mirror reflects display light. A drawing unit includes a beam generator, a scanner, an optical actuator, and a controller. The beam generator emits a beam, and the scanner scans the beam in two dimensions by moving a reflection surface to draw an image. The optical actuator changes an angle of incidence of when the beam is emitted to the scanner. The controller drives the optical actuator to change the angle of incidence such that display light distortions generated at the concave mirror are offset by display light distortions generated at the scanner.

    Abstract: Each of a plurality of optical elements that are arrayed in a lattice pattern in a screen member which diffuses a laser beam incident from a projector to guide the laser beam toward a projection surface has a curved surface on a side thereof, and the curved surface has a common convexly curved shape, and diffuses the laser beam which is emitted from the curved surface toward the projection surface. The respective optical elements include a plurality of reference elements which serve as a reference and a plurality of peripheral elements which are adjacent to the respective reference elements. The respective reference elements and the respective adjacent peripheral elements are formed by offsetting surface vertexes of the curved surfaces in a stepwise manner. Offset amounts generated between the respective reference elements and the respective adjacent peripheral elements are different from each other.

    Abstract: An optical member includes a light guide body. The light guide body has an incident surface on which an outside light is incident, a first surface having flat portions and prism portions, an incident light incident on the incident surface reaching the first surface for the first time, and a second surface arranged opposite to the flat portions. The flat portions totally reflect the incident light toward the second surface. The second surface totally reflects a reflected light reflected by the flat portion toward the first surface. The prism portion has an ejection surface to emit the incident light to outside.

    Abstract: An HUD device includes a laser scanner that projects laser light carrying a display image, and a screen member that has a plurality of optical elements arrayed in the form of a grating, and diffuses laser light which emanates from the laser scanner and enters the optical elements toward a projection surface. The optical elements have curved surfaces, which take on a convexly curved form as a common curved form, formed as their faces, and diffuse laser light which is emitted to the projection surface from the curved surfaces. A sag quantity from each of surface vertices of the curved surfaces to each of boundaries among the optical elements differs between adjoining optical elements.
