Coherent image synthesis from wave-front sensor measurements of a nonimaged laser speckle field: a laboratory demonstrations.


We report what are to our knowledge the first coherent images recovered in the laboratory from measurements made with a Shack-Hartmann wave-front sensor of the phase and amplitude of a laser speckle wave front. We discuss the design of our wave-front sensor, which can obtain the phase and amplitude of an optical field with a single intensity measurement… (More)
