Title: Reproduction of hologram
Inventor: HASHIKAWA ATSUSHI
IPC: G03H1/20
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent a reproduced hologram from being made nonuniform in the brightness by using a hologram which has the half-amplitude level of diffracted light larger than the half-amplitude level of the diffraction light of a copy hologram to be reproduced as a master hologram. SOLUTION: The reflection type hologram having desired optical characteristics is produced by a two-beam method and is used as the master hologram 21. A hologram dry plate 22 is superposed on the master hologram 21 and is irradiated with a laser beam 23, by which the hologram is copied. In such a case, the ratio (hereafter R/O ratio) of the object light quantity and reference light quantity at the time of recording the hologram is expressed by the ratio, I2 /I1 of the light intensity I2 of the diffracted light 24 and the light intensity I1 of the laser beam 23 for copying. Then, the good reproduction is made possible if the ratio is above the permissible R/O. The diffracted light intensity I2 =η2 ×I1 when the diffraction efficiency for the laser wavelength λdegrades to η2 on account of the fluctuation in the wavelength of the narrow half-amplitude hologram.  Then, the degradation in the diffraction efficiency is prevented and the uniform hologram is obtd. by specifying the η2 to the permissible R/O or above over the entire surface.
