Improvement of computer-generated hologram reconstruction by iterative Fourier method

, 2001
291-295For modifying the hologram and thereby improving the signal-to-noise ratio of the reconstructed wave front a detour phase hologram is used as the initial binary pattern from which to apply an iterative Fourier method.

Improving reconstructions of digital holograms

, 2012
Digital holography is a two step process of recording a hologram on an electronic sensor and reconstructing it numerically. This thesis makes a number of contributions to the second step of this process. These can be split into two distinct parts: A) speckle reduction in reconstructions of digital holograms (DHs), and B) modeling and overcoming partial

Iterative algorithm with a constraint condition for numerical reconstruction of a three-dimensional object from its hologram

, 2001
A novel method to obtain the three-dimensional mathematical model of a transparent object from its hologram is presented. The proposed method can numerically extract the object information from the fringe pattern of the hologram.
