摘要
目前市售胶囊内窥镜仅能观察到前方视场,而人体内肠道组织的褶皱和回环会导致大量后方视野出现盲区。设计了一种可以同时对前后方视场进行成像的胶囊物镜,该物镜的前方视场为0°~80°,侧后方视场为50°~80°。该物镜总长为15.6 mm,最大径向直径为8 mm。该物镜搭配OH02A10成像芯片可满足高分辨率(89 lp/mm处的最大截止频率大于0.5)的要求,且具有良好的成像质量。
The capsule endoscope currently on the market only images the front field of view.Furthermore,the folds and loops of intestinal tissue in the human body cause a large number of blind spots in the rear field of view.In this paper,we report the design of a capsule objective lens that simultaneously images the front(0°-80°)and the side rear(50°-80°)fields of view.The objective lens is 15.6 mm in length,and the maximum radial diameter is 8 mm.An OH02A10 imaging chip ensures a high-resolution image(maximum cut-off frequency>0.5 at 89 lp/mm)and provides good image quality.
