Photopolymer

Definition

A photopolymer is a light-sensitive material that undergoes a chemical reaction when exposed to light, particularly ultraviolet (UV) light, leading to a change in its physical properties. This characteristic makes photopolymers essential in applications like holography and holographic data storage, where they are used to record and reproduce complex optical patterns and data in three-dimensional formats.
