OPTICAL ASSEMBLY AND HEAD-UP DISPLAY HAVING A PLURALITY OF IMAGE PLANES

An optical assembly for a head-up display on a projection surface includes an imaging device, which includes at least one imaging unit, and at least one wavefront manipulator arranged in a beam path between the imaging device and the projection surface. The optical assembly is configured to generate virtual depictions in at least two different image planes, wherein the imaging device has at least a first region and a second region, wherein the imaging device and the wavefront manipulator are configured, in combination, to generate virtual depictions in a first image plane out of images generated in the first region of the imaging device and to generate virtual depictions in a second image plane out of images generated in the second region of the imaging device.
