Dual-Field Capsule Endoscope Design Based on Zemax Software
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.
