Laser scanning head-up display system for vehicles

摘要

A head-up display for a vehicle has a laser and a scanning system. An image, which is to be displayed in the field of vision of the driver of the vehicle and which is composed of individual pixels, is produced pixel-by-pixel by the laser and the scanning system. The head-up display has a projection system having a projection surface and a magnifying optical system. The projection system projects the image to be displayed onto a virtual image plane and magnifies the image in the process. The size of the pixels in the virtual image plane is smaller than the resolving ability of the human eye, which is the case for an angular distance less than 0.5′, for example.

主权项

1. A head-up display for a vehicle, comprising:
a laser and a scanning system, by which an image to be displayed in a field of view of a vehicle occupant is generated point-by-point from individual laser spots; and a projection system with a projection area and magnification optics, wherein the projection system is configured to project the image to be displayed into a virtual image plane and to magnify it in the process, wherein the projection system is configured in such a way that the size of the laser spots in the virtual image plane is smaller than the resolving power of the human eye, wherein the size of the spots in the virtual plane is smaller than 0.5′ for the observing vehicle occupant, wherein the angular distance between two adjacent spots is always less than 0.5′ for the vehicle occupant.
