摘要:
A hologram display apparatus in which chromatic aberration hardly occurs even when light of a wide bandwidth is used as a reproducing light. The apparatus has a hologram combiner 10 with a diffraction characteristic of lens, and is adapted to receive a signal light including information to be displayed and to generate, in response to the signal light, a reproduced light to be seen and acknowledged by an observer. The hologram combiner 10 has a curved surface with a constant curvature in at least one of a first direction and a second direction perpendicular to the first direction. The center 01 of curvature of the curved surface is positioned at substantially the same position of the center 02 of curvature of the lens equivalent to the hologram 11.
