Paper Abstract

A conceptually simple method for producing a hologram of a computer-specified object is to illuminate the photosensitive recording plate with a reference wave and trace out the object distribution with a point of light moved by a computer-controlled scanning system. The principal drawback is the poor signal-to-noise ratio (SNR) of the reconstructed object, because of bias buildup in the recording process. Two methods for improving reconstruction SNR are discussed in this paper: (1) maximizing the contrast of each fringe or zone-plate pattern exposing the hologram, and (2) recording intermediate holograms of portions of the object, which are then reconstructed for use in recording a final hologram of higher signal-to-bias ratio.
