Abstract:
1. An optical system with optical image stabilization comprising: at least one movement determination unit determining a movement information of the optical system; a control circuitry generating a movement compensation signal using the movement information of the optical system from the movement determination unit; and a Micro-Electro Mechanical System (MEMS) unit made by microfabrication technology and comprising a substrate, an MEMS mirror movably connected to the substrate and configured to have a motion comprising a rotation, and at least one actuation unit configured to actuating the MEMS mirror and comprising: a micro-actuator disposed on the substrate, communicatively coupled to the control circuitry, and configured to have in-plane translation in accordance with the movement compensation signal; and a micro-converter having a primary end rotatably connected to the micro-actuator, wherein the micro-actuator with the in-plane translation exerts a force on the primary end of the micro-converter and the micro-converter delivers the force to the MEMS mirror to make the MEMS mirror have a required rotation; wherein the rotation of the MEMS mirror changes optical paths of light from an object to an image plane in order to stabilize an image of the object formed on the image plane.
