Abstract :
We experimentally demonstrate the possibility of reconstructing 3-D scenes using integral imaging from very photon-starved scenes. It is shown that by using an iterative reconstruction algorithm, it is possible to reconstruct 3-D objects captured with an optical signal just above the CCD image sensors´ noise level. Three-dimensional scene reconstruction with integral images with only a few photons per pixel of the image sensor is demonstrated. Optical experimental results are presented.
