title: Absorption and phase in-line holograms: a comparison.
abstract: Improved methods of processing in-line holograms are presented for both phase and absorption modes, and the physical characteristics of the subsequent reconstructed images are compared. This comparison leads to the conclusion that the phase hologram may have advantages which have been hitherto unrecognized.
