Micromirror device

Micromirror devices are devices based on microscopically small mirrors. The mirrors are Microelectromechanical systems (MEMS), which means that their states are controlled by applying a voltage between the two electrodes around the mirror arrays. Digital micromirror devices are used in video projectors and optics and micromirror devices for light deflection and control.→ See main article digital micromirror deviceThe mirrors could not only be switched between two states, their rotation is in fact continuous. This could be used for controlling the intensity and direction of incident light. One future application is controlling the light in buildings, based on micromirrors between the two panes of Insulated glazing. The power and direction of the incident light is determined by the mirrors state, which itself is controlled electrostatically.A MEMS scanning micromirror consists of a silicon device with a millimeter-scale mirror at the center. The mirror is typically connected to flexures that allow it to oscillate on a single axis or biaxially, to project or capture light.
