本文对环形视野胶囊内窥镜的照明系统进行了研究。由于LED的光强会沿着其角位移发生变化，并与光强分布曲线一致，很难对被观察物体进行均匀照明。为此，本文利用光学设计软件ASAP建立了环形视野胶囊内窥镜LED照明系统的配光模型，并进行了优化设计。本文对环形视野胶囊内窥镜的照度均匀性进行了优化设计，从原点0.128到最优值0.603，大大提高了环形视野胶囊内窥镜的成像质量。
This paper is researching about the illumination system in ring field capsule endoscope. It is difficult to obtain the uniform illumination on the observed object because the light intensity of LED will be changed along its angular displacement and same as luminous intensity distribution curve. So we use the optical design software which is Advanced Systems Analysis Program (ASAP) to build a photometric model for the optimal design of LED illumination system in ring field capsule endoscope. In this paper, the optimal design of illumination uniformity in the ring field capsule endoscope is from origin 0.128 up to optimum 0.603 and it would advance the image quality of ring field capsule endoscope greatly.
