In this letter, we present a genetic algorithm-based approach for image retrieval through a multimode fiber in a reference-less system. Due to mode interference, when an image is illuminated at one side of a multimode fiber, the transmitted light forms a noise-like speckle pattern at the other end. With the use of a prior-measured transmission matrix of the fiber, a speckle pattern is calculated using a random input mask. By optimizing the input mask to achieve a high correlation coefficient of experimental and calculated patterns, the input mask is optimized into an image with high similarity to the original image.
