Abstract
A method for the calculation and storage of a computer-generated multilayer hologram with more than or equal to 2 holograms includes the following steps. Field Aof a readout beam and field Ain the reflection plane are preset as mathematical functions. Except for the hologram to be calculated, all the other holograms of the layer structure are also preset as mathematical functions. Fields A/Aare then calculated on both sides of hologram h, as a result of which hologram function h, is calculated by forming a quotient from fields A/A.
