Abstract

An auto focus intraoral camera includes an illumination module for providing illuminating light, an imager (307), and a lens system for collecting light reflected from an object and focusing the light onto the imager, wherein said lens system further comprises at least one liquid lens (100) including a vessel filled with a first liquid (103), and a second liquid (101) being in contact with said first liquid, the first and second liquids being immiscible, of different optical indexes, and of substantially same density; wherein the lens system further includes a driver integrated circuit (303) applying variable voltage to control the focal length of said lens. According to the present application, a compact auto focus intraoral camera with a small size and simple structure is provided, which decreases the camera complexity and improve the performance.
