A kind of interference fringe three-dimensional mold manufacturing method and its mold and replication method

Abstract

The disclosure relates to the field of holographic technology, and specifically provides a method for manufacturing an interference fringe mold and a mold and replication method thereof. The method comprises the following steps: (1) composite coherent wave sensitive material on the surface of a three-dimensional mold; (2) record interference fringes through a three-dimensional optical path, so that the composite sensitive material layer of the three-dimensional mold is loaded with interference fringes; the recording method of the three-dimensional optical path is as follows: The characteristics of recording information content Set up a suitable three-dimensional space optical path, and record information on the sensitive material layer according to requirements; (3) Repeat the three-dimensional mold with interference fringes for multiple inverse copies, and finally obtain an interference fringe mold with a certain hardness. It solves the problems in the prior art that the holographic illusion pattern is deformed or disappears due to the deformation of the plane template into a three-dimensional template to copy interference fringes, and the copied holographic illusion image has only a single viewing direction and a narrow viewing angle.

Description

technical field [0001] The disclosure relates to the field of holographic technology, and specifically provides a method for manufacturing an interference fringe mold and a mold and replication method thereof. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the popularization of anti-counterfeiting technology and holographic color handicraft technology, people began to use the interference phenomenon to achieve beautiful, anti-counterfeiting and other needs. Therefore, the interference fringe replication technology came into being. The so-called interference fringe replication technology is to record the interference fringe information on the template. Then the interference fringes are engraved using the template, and the engraved interference fringes are exactly the same as the original interference fringes. Of course, the template is usual...

Problems solved by technology

[0004] In the prior art, the processing of the holographic illusion pattern is usually carried out on the plane template. In the prior art, there is a method of re-engraving on the three-dimensional template. Specifically, it is first reproduced on the plane template, and then the plane template is transformed into a three-dimensional template, but the inventor found that the holographic illusion pattern on the deformed three-dimensional template was deformed or disappeared due to the damage of the interference fringe deformation, and the ideal holographic illusion three-dimensional reproduction could not be completed

[0005] The inventor also found that in the process of preparing holographic illusion patterns in the prior art, the optical path is mostly designed in one plane, and the interference fringes are recorded on the plane template from a single plane direction, resulting in a recorded holographic illusion image with only a narrow viewing angle And a single viewing direction, that is, the recorded information cannot be seen in other directions, and it is difficult to meet the visual requirements
