Reconstruction Enhancements with Optical Scanning Holography

Optical scanning holography (OSH) [1] has the benefit of recording the entire three-dimensional (3-D) volume of a specimen in the form of a two-dimensional (2-D) hologram. Reconstruction of the original volume can be accomplished by applying digital reconstruction or decoding techniques to the recorded hologram. Accurate reconstruction of the 3-D volume and more specifically, the individual 2-D optical sections without artifacts such as out-of-focus haze from adjacent sections has been the focus of much work including algorithms, optical techniques, and combinations of the two. This dissertation presents several different techniques for enhancing the reconstruction of a recorded specimen and its optical sections including the use of optical coding and phase filtering techniques in the traditional OSH optical system.
