Spatial light modulation

Spatial light modulation refers to the technique of controlling light in a specific area or pattern. It involves devices, like liquid crystal displays or digital micromirror devices, that can change the intensity, color, or phase of light across a surface. This technology is widely used in projectors and optical systems, allowing for the creation of images, patterns, or effects in real-time. By manipulating light spatially, we can enhance visual displays, improve imaging techniques, or even enable advanced applications in areas like telecommunications and virtual reality.
