Abstract (en)
[origin: WO2022194466A1] The invention relates to a wavefront manipulator (3) to be arranged in the beam path (20) of a head-up display (10) between a projection lens (2) and a curved projection surface (14) having a number of fixed characteristics, the wavefront manipulator (3) comprising a plurality of optical elements (7, 8, 9, 22) with different representational functions, each representational function at least partly correcting an aberration caused by at least one fixed characteristic of the curved projection surface (14).
