We present a simple reconstruction algorithm for three-dimensional (3D
) incoherent source distributions imaged by a laterally scanned pinhol
e camera. We consider digital sampling of multiple pinhole images for
3D reconstruction and implement an experimental demonstration with lat
eral resolution of 2 x 10(-3) rad and longitudinal resolution of appro
ximately 0.14z(2) m, where z is the object-to-pinhole distance in mete
rs. (C) 1998 Optical Society of America.
