Dynamic vision sensing system with a static capturing mode

A polarization-controlled optical module, comprising:

• a) a circular polarizer adapted to filter a polarization from an incoming light to the circular polarizer at a predetermined handedness;
• b) a GPA (Geometric Phase Axicon) module located after the circular polarizer on an optical path;
• wherein the GPA module is adapted to alter the focusing of an environmental scene inputted to the circular polarizer, as driven by a control signal.

A method of capturing a static object using a dynamic vision sensor, comprising the steps of:

• a) triggering, by an optical module which is electronically controllable, an intensity change in an environment captured by the dynamic vision sensor, wherein, upon detecting no change of motion in the environment, an Artificial Intelligence (AI) recognition module connected to the dynamic vision sensor sends a command to the optical module, and the optical module triggers the intensity change in response to the command;
• and
• b) observing the static object in the environment by the dynamic vision sensor.
