摘要： An optical device for displaying a condensing mark includes a light source, and an optical element for condensing light emitted from the light source onto an irradiated surface. The deflection surface of the optical element is divided into a plurality of regions. The light emitted through the respective regions on the deflection surface of the optical element forms partial irradiation images corresponding to the respective regions on the deflection surface of the irradiated surface. The respective partial irradiation images are combined into at least one condensing mark on the irradiated surface.

摘要： An information display apparatus is provided. The information display apparatus includes: a display configured to display video information of a virtual image; and a virtual image optical system configured to display a virtual image at a front of conveyance by reflecting light emitted from the display. The system includes a concave mirror and an optical element. The optical element is arranged between the display and the concave mirror, and is configured to correct distortion of the virtual image obtained in accordance with a viewpoint position of a driver. The information display apparatus further includes means for forming the virtual image generated by reflecting a video light flux by means of front and back surfaces of the windshield in front of a position of a driver's line of sight in a region where a virtual image distance exceeds a driver's determination limit range or a region around the determination limit range.

摘要： A HUD system and light source apparatus can be manufactured with miniaturization at low cost. A head-up display apparatus includes: an image display apparatus generating image light to be projected; an optical system performing predetermined correction to the image light emitted from the image display apparatus; and a concave mirror reflecting the image light corrected by the optical system to project it onto a windshield or combiner. The image display apparatus includes: a solid light source; a collimating optical system converting, into parallel light, the light from the solid light source; a lighting optical system configured by an optical member that polarizes a direction of a light beam generated by the collimating optical system and simultaneously expands a width of the light beam; and a display apparatus, the image display apparatus being configured to be arranged across and opposite the optical system on an optical axis of the concave mirror.

摘要： Provided is a compact light source device that can be manufactured at a low cost and is suitable as an illumination light source for a display device of an electronic device such as an HUD or an ultra-compact projector. This light source device includes a solid-state light source, a collimating optical system that converts light having exited the solid-state light source into a substantially collimated light; and a light guide that allows the light having exited the collimating optical system to enter and allows this light to exit in a direction that differs from a direction of entry. The light source device further includes a polarization converting element that aligns polarization directions of the light exiting the light guide into one direction.
