Abstract
The present invention provides a fast optical shutter function by use of the fast movement of the micromirrors. In a micromirror array lens (MMAL), all the micromirrors reflect the incident light to form an image on the image plane. If the micromirrors reflect the incident light out of the optical sensor area, then the optical sensor can not have any optical signal just like the incident light blocked. By just changing the beam path by MMAL motion, the micromirror array lens has a function for optical shutter.
