Title:
METHOD FOR PRINTING HOLOGRAM WITHOUT DISTORTION BY INTERFERENCE PATTERN GENERATED BY INTERNAL REFLECTION
Document Type and Number:
WIPO Patent Application WO/2022/124536
Kind Code:
A1
Abstract:
Provided is a method for printing a hologram without distortion by an interference pattern generated by internal reflection A holographic printing method according to an embodiment of the present invention comprises: generating a holographic fringe pattern; and recording the generated holographic fringe pattern in a holographic material attached to a glass plate, wherein the thickness of the glass plate is such that, when reference light incident on the holographic material to record the holographic fringe pattern is reflected from the rear surface of the glass plate, the reference light passes through a position deviated from a recording area of the holographic material. Accordingly, noise is reduced by preventing the occurrence of an interference pattern other than the original interference pattern of the object light/reference light.
