Small Capturing system of Three-dimensional image Using Compound Optics

We have developed a small 3D image capturing system using compound optics. 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. Digital processing of the captured multiple images is used to extract the surface profile. Preliminary experiments were executed on evaluation system to verify the principles of the system and to clarify the issues related to its implementation.
