Micro-mirrors are tiny reflective surfaces, often measuring just a few micrometers in size. They are commonly used in devices like digital projectors and displays, where they can tilt to control light direction. This technology allows for high-resolution images and efficient light management. These mirrors are typically found in systems like Digital Light Processing (DLP) and MEMS (Micro-Electro-Mechanical Systems). By rapidly adjusting their angles, micro-mirrors can create various shades and colors, enhancing visual experiences in everything from televisions to smartphones. Their compact size and precise control make them essential in modern optical applications.
