Abstract
Security holograms, diffractive optical elements known for their intricate 3D visuals, are a cornerstone of brand protection. However, their effectiveness hinges on robust authentication methods. This work explores the critical role of illumination in hologram visualization for enhanced authentication. We investigate the impact of illumination angle and capture stage on the clarity of the hologram's visual features. An experimental setup utilizing an LED light source, and a smartphone camera allows for systematic analysis of illumination angles. Laser light is also explored as a potential authentication tool. By combining observations, detailed documentation, and the potential of Artificial Intelligence (AI), this research aims to identify the optimal illumination conditions that maximize hologram visualization, facilitating efficient and reliable authentication workflows. This approach paves the way for improved security in document and product authentication, ultimately strengthening consumer trust and brand reputation.
