Abstract
The present invention relates to a multi-depth-of-field light-sensing device, a system, a depth of field extension method, and an optical imaging system. The multi-depth-of-field light-sensing device includes at least two light-sensing pixel layers capable of inducing a light source, where the at least two light-sensing pixel layers are arranged at an interval of a preset distance, so that different light signals from a lens at a specific distance from the light-sensing device are focused to the different light-sensing pixel layers. The multi-depth-of-field light-sensing device of the present invention can implement automatic focusing without using any electrically operated mechanism or complex and precise mechanical component, and have good depth of field extension performance.
