Abstract

This research proposes a newly developed method to high zoom lens for mobile phone use, which the overall length is restricted in mobile phone size acceptable. Generally speaking, the optical design with liquid lens might be more complicated in optimization than traditional optics; not only because aspherical coefficient in liquid lens element is difficult to be defined and measured, but also because efficient optics layout needs more efforts to study in the near future. The paper mainly utilizes liquid lens in order to short total length; two liquid lens elements must be included. Besides consider total length, Lateral aberration also is very important. Lateral aberration will play a significant role in the Modulation Transfer function (MTF), so, the optical design will be able to arise very big, and that the many kinds of chromatics aberration with two groups of liquid lens. Using Digital Signal Processing technology principal factor why this also is.
