Abstract

We consider the recently proposed double phase encoding system, and we analyze the influence of a perturbation of the coded image on the decoded image. Since in optical implementation, the intensity of the decoded image is measured at the output of the decoding system, we express the signal-to-noise ratio (SNR) on the intensity decoded image as a function of the amplitude SNR of the complex coded image. We show that there exists a simple relation between these two SNR's, and that this relation is quasi- independent of the nature of the coded image perturbation. The results presented in this paper could help characterizing the precision level of the components of the optical decoding system necessary to reach a pre-defined quality level of the decoded image.
