Computational confocal tomography for simultaneous reconstruction of objects, occlusions, and aberrations

We introduce and experimentally validate a computational imaging technique that employs confocal scanning and coherent detection in the Fourier domain. We show how this method may be used to tomographically reconstruct attenuation, aberration, and even occlusion. We also show how these image parameters may be combined with the conventional confocal image reconstruction of the object reflectivity. We demonstrate the method experimentally by imaging a sample consisting of an occlusion above a mirror of varying reflectivity. © 2010 Optical Society of America OCIS codes: 110.1758, 110.6955.
