About

P. A. M. dos Santos is a researcher specializing in optical physics and holography, with a focused interest in photorefractive materials and their applications for secure information processing. Their major contributions lie in the development of novel techniques for generating numerical codes using dynamic moiré fringe patterns. In their 2013 work, they proposed photorefractive holographic moiré-like patterns as secure numerical code generators, demonstrating a method that could be useful for data storage or transmission. This was further refined in a 2014 study, where they employed low-frequency moiré fringe patterns created by superimposing two sinusoidal gratings in a Bi₁₂TiO₂₀ photorefractive crystal. While their citation counts are modest—3 and 2 citations respectively—these papers represent foundational steps in merging holographic interferometry with optical security. Dos Santos’s work is notable for its creative integration of classical moiré phenomena with modern photorefractive holography, offering a unique approach to generating secure, dynamic codes. Their research is particularly relevant for students and researchers exploring optical encryption, holographic data storage, and non-conventional methods for information encoding.
