Storage medium having the calculation method of the multi-layer hologram, a multilayer hologram and a method for manufacturing a multilayer hologram

摘要

The present invention relates to a method of computing computer-generated holograms with a hologram of the number of 2 or more. Field A _R in the playback level and the field A ₀ of the readout beam is given as a mathematical function. Additional holograms of all layers to make a hologram that is also calculated, given as a mathematical function. Next, field A _i⁺ / A _i^- is calculated on both sides of the hologram h _i that is determined, then the hologram function h _i is A _i⁺ / A _i by forming quotient ^- is calculated from. The present invention also relates to a storage medium having holographic multilayer hologram produced by this method and a method for producing a multilayer hologram. [Selection] Figure Figure 1
