Abstract
A head up display arrangement for a motor vehicle includes a picture generation unit producing a light field. A digital micromirror device is positioned to reflect the light field. The digital micromirror device includes an array of mirrors each having an individually adjustable orientation. An electronic processor is communicatively coupled to the digital micromirror device and individually adjusts the orientation of each mirror such that the light field reflected by the digital micromirror device is visible to the driver as a virtual image.
