Recently, demand for acquisition of 3D optical information using optical sensors in a 2D arrangement is rapidly increasing with development of computational processing devices and optical systems. Among various approaches, light field cameras are promising in acquiring 3D position and angle information of objects. Unlike the existing light field cameras using micro-lens arrays, our approach is firstly taking the images at different focal points and then extracting 4D light field information using the new unique algorithm developed in this study. This new algorithm allows to extract the specific light field information originating from a specific single point source among the mixed light field information in the space without iteration typically required image processing. This new approach for extracting 4D light field information is not limited by point-spread-function (PSF).
