Spatial Light Modulators (SLMs) are devices that control the amplitude, phase, or polarization of light waves. They are commonly used in applications like display technology, optical communication, and holography. SLMs can manipulate light in real-time, allowing for dynamic image projection and advanced optical processing. These devices typically consist of an array of tiny pixels that can be individually controlled. By adjusting each pixel, SLMs can create complex light patterns, making them essential in fields such as adaptive optics and laser beam shaping. Their versatility enables innovations in both scientific research and commercial products.
