Abstract

Integral photography offers an interesting alternative to holography for recording and displaying 3-dimensional information. This paper derives the optimum size of the lenslet in the lenticular screen and derives a resolution limitation for integral photography which for conventional objects is comparable to the resolution of a TV picture. The number of resolvable spots needed to record an integral photograph is also computed and it is shown that this number is proportional to the fourth power of the (linear) resolution in the reconstruction.
