Area of Science:

Optics and Photonics
Materials Science
Security Technology

Background:

Traditional security features can be counterfeited.
There is a need for advanced authentication methods for valuable items.
Micro-optic systems offer potential for high-security applications.

Purpose of the Study:

To investigate the reflective glass pattern imaging effect for synthetic 3D image formation.
To develop a novel security authentication device.
To evaluate the feasibility of micro-optic systems on thin polyester films.

Main Methods:

Experimental investigation of reflective glass pattern imaging.
Integration of randomly distributed reflective elements and micropatterns on polyester film.
Utilizing a novel gravure-like doctor blading technique for high-resolution fabrication (up to 12,000 dpi).

Main Results:

A vivid 3D image is created, appearing to float above the substrate.
The reflective-type micro-optic system is realized on a thin substrate.
The system is immune to external stains due to its flat working plane.
High resolution and stringent 2D alignment were achieved.

Conclusions:

The reflective glass pattern imaging effect is a viable method for creating synthetic 3D security images.
This technology can be applied to document security, banknotes, and other valuable items.
The developed technique offers a cost-effective and robust solution for anti-counterfeiting.
