photorefractive materials

Photorefractive materials are special substances that change their optical properties—like how they bend or focus light—when exposed to light patterns. When illuminated with specific light patterns, they develop regions with different electrical charges, which in turn alter how light passes through or reflects inside them. This dynamic change allows these materials to be used for tasks such as correcting optical distortions, data storage, or creating adjustable lenses. Their ability to adapt based on the light they receive makes them useful in advanced optical technologies, including holography and dynamic light manipulation systems.
