摘　　要：设计了一种具有大角度照明的胶囊内窥镜,通过特定的结构将中央的光能部分分布到周围出光角度大的照明区域,提高胶囊内窥镜的照明角度,满足其140°的视场角要求。应用3D结构设计软件Solidworks对特定的透明泡壳进行建模,光线追迹软件Tracepro进行光学仿真,分析了离光源不同位置的照度,结果表明此结构可以达到内窥镜对视场角140°的要求。Acapsule endoscope with large illumination angles is designed to allow light energy at the center be mainly distributed into illuminated area with greater light-emitting angles through a specific structure,which enlarges the illumination angles and meets the requirement of a field of view of 140°.The light-transmitting bulb shell was modeled by 3D software Solidworks,and the optical simulation was achieved by ray tracing software Tracepro.The luminous intensity distributions at different distances from the light source were analyzed,and the results showed that the improved capsule endoscopy can realize a field of view of 140°.
