- Abstract:
- Abstract: A capsule 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°.
