ABSTRACT:
A head-up display having an image source for producing imaging illumination, an optical combiner for partially reflecting the imaging illumination to produce a virtual image of the image source that is viewable by the operator of the vehicle, and a polarizer which can be controllably interposed between the image source and the optical combiner for nighttime use. The polarizer tends to block the illumination that otherwise would produce objectionable ghost images.
