Abstract

Problems of the quality improvement of holographic images and the reconstruction time reduction are discussed. The convolution and Fresnel approaches are presented. For both methods the algorithm improvement is proposed. Basing on the special transmittance function calculating the computation time is significantly decreased. For the Fresnel approximation the autocorrelation factor from the reconstructed image is removed. The presented ideas are illustrated by exemplary images for each step of computation. Advantages and disadvantages of the methods are discussed.
