We present a technique of photorefractiveffects for white-light incoherent-to-coherent conversion and oneway image transmission through a thick turbulent medium. A high resolution photorefractive incoherent-tocoherent optical converter was realized even for white light transmission by applying the same technique as we used in incoherent laser beam transmission. Analogical reconstructed laser images with high-fidelity were obtained, correcting the image blurring due to the thick turbulent medium.
