| Abstract: | The paper introduced the basic form of the motion of the cam, the optical zoom system working principle and the optical path calculation process. It used UG 3D design software as tool to design the cam contour, and got finite element analysis on the structure of cam, and accurately restored the law of motion of the continuous zoom optical system in the zoom group, at the same time improved the design precision of cam contour. |
