Abstract
Miniaturization is the key point to design image system for portable devices. Motor-driven lens technique is the traditional way to achieve auto-focus and zoom functions. Nevertheless, systems with moving parts are difficult to downscale. A solution presented in this paper has more potential to downscale and maintain high optical performance simultaneously by combining reflective optics and MEMS deformable mirror. The system we designed with MEMS deformable mirror is a 2M pixel auto-focus image system which is only 5.4mm in thickness before packaging and 6.7mm in thickness after packaging. © 2009 Copyright SPIE - The International Society for Optical Engineering.
