Abstract (en)

[origin: WO2022268751A1] Disclosed is an optical assembly (11) for a head-up display (10) on a projection surface (5), comprising an imaging device (22), which comprises at least one imaging unit (26, 27), and at least one wavefront manipulator (23) arranged in the beam path between the imaging device (22) and the projection surface (5). The optical assembly (11) is configured to generate virtual depictions (8, 18) in at least two different image planes, wherein the imaging device (22) has at least a first region (26, 28) and a second region (27, 29), wherein the imaging device (22) and the wavefront manipulator (23) are configured, in combination, to generate virtual depictions (8) in a first image plane out of images generated in the first region (26, 28) of the imaging device (22) and to generate virtual depictions (18) in a second image plane out of images generated in the second region (27, 29) of the imaging device (22).
