摘　　要：研究了采用新型的GRIN透镜的微胶囊内窥镜成像的工作原理 根据近轴子午光线方程 ,用矩阵分析法分析GRIN透镜成像原理 ,并提出自动调焦、CCD光电转换、图像传送和无线传送电能等的实现方法A new microcapsule endoscope using a GRIN lens is introduced in this paper. According to meridian equation for paraxial rays, GRIN lens imaging principle by matrix analysis method is analyzed. And besides, auto-focusing, how to convert light to electricity using CCD, image transmission, power transmission by wireless and so on are also discussed. All of these provide the essential principle foundation and important technique methods for the research of minitype instruments of biomedicine.
