Three-dimensional source reconstruction with a scanned pinhole camera

We present a simple reconstruction algorithm for three-dimensional (3D) incoherent source distributions imaged by a laterally scanned pinhole camera. We consider digital sampling of multiple pinhole images for 3D reconstruction and implement an experimental demonstration with lateral resolution of 2 x 10(-3) rad and longitudinal resolution of approximately 0.14z(2) m, where z is the object-to-pinhole distance in meters.
