Research Abstract |
Lensless coherent diffractive imaging has attracted considerable attention during the past decade in the fields of x-ray and electron imaging. Recently, we have proposed a novel method of coherent diffractive imaging using a deterministic phase-retrieval method with an aperture-array filter, which allows for the reconstructions of the modulus and the phase of an object from a single diffraction intensity measured with the filter. In this study, the effectiveness of our method has been demonstrated by the experiments at optical wavelengths under the conditions of the rigorous diffraction as well as the Fresnel diffraction approximation.
