Abstract
A head-up display is configured to project an image on a transparent reflection member to cause an observer to visually recognize a virtual image, and includes a display device configured to display the image, and a projection optical system configured to project the image displayed by the display device as the virtual image for the observer. The projection optical system is configured to form the image as an intermediate image, and includes a first optical element configured to condense light, a first lens configured to condense light, and a second optical element configured to diffuse light. The first optical element, the first lens, and the second optical element are disposed in this order along an optical path from the display device.
Claims9
A head-up display comprising:
- a device configured to emit beams for forming a projection image from an original image;
- a first mirror configured to reflect the beams emitted from the device;
- a first lens configured to condense the beams reflected by the first mirror;
- a second mirror configured to reflect the beams and form an intermediate image;
- and
- a third mirror configured to reflect the beams that form the intermediate image to a windshield as the projection image, wherein:
- the first mirror, the first lens, the second mirror, and the third mirror are disposed in this order along an optical path to the windshield, and
- the intermediate image is an aerial image formed in a space on the optical path between the second mirror and the third mirror.
