    摘要： An integrated optical auto focus and zooming system is provided, which includes a first optical lens, a first hollow casing, a second hollow casing, a plurality of piezoelectric elements. The first optical lens is placed in the first hollow casing, the first hollow casing and the second hollow casing are screwed with each other, and the plurality of piezoelectric elements are attached either on the first hollow casing or the second hollow casing. Upon the excitation of mechanical vibrations by the plurality of piezoelectric elements, a traveling wave is generated on the attached casing, so as to drive the other casing to rotate and then to move axially. Additional lens groups and casings can be added in the same way so to achieve multiple relative motions between lens groups and image sensor, and thus achieving the objectives of focusing and zooming. The present invention integrates the motor into the lens and hence eliminates the transmission mechanism, leading to simple structure, high efficiency, and multiple advantages in size, cost, and efficiency, etc., and thus can be very useful.
