“…However, it was not until the invention of the laser in 1960 and its commercialization in 1962 that holography proved to be a highly productive and attractive area of research. Since then, the many applications of holography in many different *a.belendez@ua.es; https://www.ua.es scientific and technical areas have given rise to "hot topics" [12,13] and the basic principles involved in hologram recording and reconstruction continue to give rise to exciting innovations in a wide range of areas: three-dimensional imaging, holographic interferometry, pattern recognition, image processing, holographic portraits, communications, optical elements, head-up displays, acoustic holography, particle detection, optical storage, solar energy conversion, optical encoding, digital holography, security, packaging, sensing, etc.…”
