Optical system for a head-up display installed in a motor vehicle has an image-generating device, image-mixing device, a beam splitter and an image-evaluating device

摘要

An image-generating device (4) creates an image and emits beams of light (12) for an image to be directed onto an image-mixing device (3) via lenses (5,8) so that the image-mixing device/vehicle windscreen blends a virtual image (10) with visual impressions of a person's (2) real surroundings so as to make it distinguishable. A beam splitter (6) fits in a beam path between the image-generating device and the image-mixing device and has an optical sensor (7).
