Holographic imaging lens for e.g. front panel of airplane, has reflection holograms forming optical unit and directly arranged one upon other, where one of reflection hologram is provided by imaging of other hologram

摘要

The lens has reflection holograms (1, 3) forming an optical unit and following an optical path directly on each other, where the holograms are directly arranged one upon the other and form a laminar unit. One of the reflection holograms (1) is provided by the imaging of the other hologram (3). An angle of incidence in a reflection hologram and an incidence condition of the light are determined, under which the reflection hologram is reconstructed and the imaging is effected. Independent claims are also included for the following: (1) a representation device for masking information in a review area of a front panel of a vehicle and airplane (2) a method for producing a holographic imaging device.
