| Popis: | 95 In recent years, the volume of the cell-phone has been smaller than before, so strictly limit the length of the whole lens in the design of the cell-phone lens. The research of this thesis is mainly designed for the lens design of the cell-phone. Make the design of cell-phone lens more optimized according to some patents and articles based on aberration theory and the use of optical design software ZEMAX. As for the initial structure of the optimization, try to shorten the effective focus length and the total length of optical system, to narrow the assembling volume of the module of the lens, and to improve the quality of image, such as the improvement of MTF and the reduction of distortion and so on. As for the zoom, propose the method different from the traditional design in zoom：Change radius, thickness, and distance between the lens to get the different effective focuses. Finally, according to the above-mentioned design, the volume of the cell phone is smaller than before and the quality of image is higher. And the lens of the cell-phones has higher zoom ratio. |
