Mobiles are playing an important role in communication for daily life and become necessaries for people. Along with the progress of the digital cameras in recent years, it is feasible to combine mobiles and cameras for new products. Because of consumers’ raising the requirement of the revolution for mobile camera, the function of the digit camera can be replaced in the near future. Mobile camera with only auto-focusing function is not filling consumers’ need anymore. With the size of mobile devices getting smaller and smaller, the displacement-to-thickness ratio is getting larger that makes mechanical motor system difficult to package inside a mobile devices. We propose a design using deformable mirror rather than actuator. Using deformable mirror achieves long light path in thin products because of folded light-path design. In the thesis, we build up two systems for concept proof of auto-focusing and zooming using deformable mirror. We also design a prototype for real lens module that is feasible for commercial use. Furthermore, deformable mirrors have the advantages of low color dispersion, but typically the optical power range of commercially available devices is relatively small. We also present an organic deformable mirror that can operate over a larger power range of 30-diopter, which are two orders of magnitude higher than silicon/silicon nitride device, can integrate into optical lens module. Therefore, deformable mirror is well suited for compact imaging system.
