Title:
多層ホログラムの計算方法、多層ホログラムの製造方法及び多層ホログラムを有する記憶媒体
Document Type and Number:
Japanese Patent JP2004538519
Kind Code:
A
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 AO of a readout beam and field AR in 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+/A- are then calculated on both sides of hologram hi, as a result of which hologram function hi, is calculated by forming a quotient from fields A+/A-.
