| Summary: | 碩士 === 國立中央大學 === 光電科學研究所碩士在職專班 === 100 === This research, which is based on the patent M272096 of Republic of China, aimed to design the three million pixels camera of 60-degree angle of view by using three plastic lens and sensor OV3630. In the process of designing, the researcher did not eliminate the extremum of lens intentionally. Moreover, comparative illumination was raised by controlling off-axis number aperture and the curve of distortion through real ray high. Furthermore, on the quality of imaging, the researcher limited the real ray high of margin ray, which was aiming respectively to the X and Y direction, and that is accompanied by standard merit function. After optimizing, the full length of this lens is 7.45114 mm, comparative illumination is greater than 62%, and the absolute value of optical distortion was controlled no more than 2%; moreover, all the MTF within 113 lps/mm of spatial frequency is greater than 47%. The results of this device above-mentioned were all qualified to the target of imaging quality.
