Abstract: | 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. |
