Comparative Analysis of Optical Arrangements Intended for Recording of Holograms with Optically Encoded and Concealed Images

摘要

In the paper we analyze some optical arrangements intended for recording of holograms with optical encoding of the image. In the first section on the basis of the Opto-electronic systems theory we are considering the processes of hologram recording and reconstruction with optically encoded images for Fourier and Fresnel hologram recording schemes with encoding mask in reference and subject branches. In the second section the detailed analysis of these schemes with encoding mask consisting of a set of secondary point sources placed in reference branch is made. The results of influence of optical elements installing inaccuracy in the arrangement of image retrieval on a quality of this image are obtained. The hologram recording arrangement for the further studies on the base of the analysis is chosen. In the third section we estimate a signal to noise ratio in the image plane for the arrangements selected. Analysis of multiplexing holograms using possibility with image optical encoding is made.
