Optimized Design of Capsule Endoscopy Lens Based on ZEMAX

摘要：

Abstract - At present,the application of Capsule endoscopy (CE)faces some extremely important issues,e.g.,image quality and field of view,which causing difficulties for doctors to make an accurate diagnosis.Its a technical difficulty to acquire wide-angle internal intestinal image under the volume restrictions of CE.In this paper,a simple and practical design of CE lens aimed to clearer and wider-angle intestine image is proposed based on ZEMAX.The new lens improves the field curvature and distortion with the application of special transparent cover and aspheric technology.The optimal design has a FOV of 105 ° ,and the F number is 2.8.The modulation transfer function (MTF)is about 40%at 45lp/mm,and the distortion is under 15%.It can perfectly satisfy the requirements of the CE lens,and provide high-quality image for 1/4 CMOS image sensor with effective pixels of 1600×1200 and pixel size of 2.2μm.
