Abstract

In a previous publication we introduced a new photorefractive four-wave mixing deconvolution, FWMD, image correction approach for achieving one-way image transmission through an aberrating medium. In this paper we extend our work to include additional image degradations and more test cases. We characterize the performance as a function of the input beam ratios for four metrics: signal-to-noise ratio (SNR), normalized mean-square-error (NMSE), edge restoration (ER), and the peak-to-total energy ratio (PTE). In our characterization we color-code the best beam-intensity ratio 2D region(s) for each of the above metrics. Test cases are simulated at the optimal values of the beam-intensity ratios.
