Abstract

We propose and demonstrate a photorefractive real-time holographic deconvolution technique for adaptive one-way image transmission through aberrating media. In contrast with preceding methods, which have typically required various coding of the exact phase or two way image transmission for correcting phase distortion, our technique relies on one-way image transmission through using exact phase information. Our technique can simultaneously correct both amplitude and phase distortions and provide substantial noise filtering. The nonlinearity of the photorefractive medium also helps to enhance the signal-to-noise ratio (SNR). And is thus superior to previous methods. We demonstrate our results through both experiment and computer simulation for different aberrators.
