Volume holography is a branch of holography that utilizes the entire volume of a photosensitive medium to record and reconstruct three-dimensional images. This technique differs from traditional holography, which typically involves recording images on the surface of a medium. Volume holography has applications in areas such as data storage, optical security, and three-dimensional display technology. It allows for the storage of large amounts of data in a compact space and enables the creation of realistic-looking three-dimensional images. Researchers in the field of volume holography are focused on developing new materials and techniques to improve the efficiency and quality of holographic recordings, as well as exploring new applications for this technology.
