Abstract
An optical system includes a light-receiving plane, a lens group, a pixel-based diaphragm, and a driving unit. The lens group is configured to direct an incident light to the light receiving plane. The pixel-based diaphragm is at an aperture stop of the lens group. The pixel-based diaphragm includes a first substrate coated with pixelated electrodes; a second substrate coated with an electrode; and an active medium layer between the first substrate and the second substrate. The driving unit is electrically coupled with the pixel-based diaphragm and configured to control the pixel-based diaphragm to have a first light transmitting pattern at a first time duration and a second light transmitting pattern at a second time duration, wherein the first light transmitting pattern is different from the second light transmitting pattern.
