How fast can one numerically reconstruct digitally recorded holograms?

摘要

Results of comparative study of the computational complexity of different algorithms for numerical reconstruction of electronically recorded holograms are presented and discussed. The following algorithms were compared: different types of Fourier and convolutional algorithms and a new universal DCT-based algorithm, in terms of the number of operations. Based on the comparison results, the feasibility of real-time implementation of numerical reconstruction of holograms is evaluated.
