PRODUCTION METHOD OF HOLOGRAM AND PRODUCTION METHOD OF COLOR HOLOGRAM

摘要

PROBLEM TO BE SOLVED: To provide a production method of a hologram in which desired diffraction characteristics are imparted with high accuracy.;SOLUTION: The production method of a hologram includes a step of exposing a photosensitive material to reference light and object light in a first wavelength region from different sides to each other. An incident angle of the reference light to the photosensitive material and an incident angle of the object light to the photosensitive material are determined by: preparing an examination hologram by a production method including a step of exposing an examination photosensitive material to reference light and object light in the first wavelength region from different sides to each other; examining diffraction characteristics of the prepared examination hologram; and considering incident angles of the reference light and the object light to the examination photosensitive material, an incident angle of reproducing illumination light to the examination hologram and a diffraction angle of the reproducing illumination light in the examination hologram.;COPYRIGHT: (C)2014,JPO&INPIT
