A research study group led by Teacher Junsuk Rho at POSTECH (Pohang College of Scientific Research and Innovation) has actually created a protected hologram system that runs exclusively based upon the wavelength of light and the spacing in between metasurface layers. The modern technology makes hacking and counterfeiting basically difficult, and is anticipated to be commonly taken on for safety cards, anti-counterfeiting, and armed forces interactions. The paper is released in the journal Advanced Practical Products.
