Title:
HOLOGRAM RECORDING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/1997/015871
Kind Code:
A1
Abstract:
A high-quality hologram in which substantially no noise light occurs during the reproduction and permeation thereof is put on the market. The intensity of reference light during the recording of a hologram and a ratio r of the intensity of the reference light to that of object light are determined so that an interference fringe formed by the object light and reference light constitutes a suitable first intensity SR within the latitude of a hologram; a ratio N/SR of a second intensity of an interference fringe formed by a plurality of wave fronts of the object light to the first intensity becomes not higher than a predetermined level Nc; and a ratio N/SR of a third intensity of an interference fringe formed by the secondary light, which is reproduced by the interference fringe formed by a plurality of wave fronts of the object light, and reference light to the first intensity becomes not higher than the predetermined level Nc.
