Three dimensional measurement of cancer by Compound Eye system

We have developed three-dimensional endoscopic system by Compound Eye. The system consists of micro lens array and an image sensor. As a micro lens array, we used GRIN lens array. It decreases a cross talk which lens-to-lens occurs on image sensor. This module uses a micro-lens array to form multiple images, which are captured on a photo-detector array. Digital processing of the captured multiple images is used to extract the surface profile. Preliminary experiments were executed on an evaluation system to verify the principles of the system. In this paper, we have proposed three dimensional endoscopic system using GRIN lens array. A compound-eye imaging system and post-processing are employed. Experimental results verify the principle of the proposed method for cancer and show the potential capability of the proposed system architecture.
