spatial light modulators

Spatial light modulators (SLMs) are devices that control light in specific ways to create images or patterns. They consist of a surface with many tiny pixels that can change light intensity, color, or phase when electronic signals are applied. SLMs are often used in projectors, optical devices, and advanced imaging systems, enabling applications such as 3D displays, holography, and adaptive optics. Essentially, SLMs act like a digital canvas for light, allowing for precise manipulation to achieve desired visual effects or improve image quality in various technologies.
