Use of a temporal approach to the three-dimensional image formation of a distant rough nonplanar object

A method is proposed to reconstruct three-dimensional images of a distant nonplanar rough object by the speckle pattern of its flat image, which is calculated using the temporal approach based on the time correlation function of probe radiation with a coherence length smaller than the size of the probed object. We analyse the influence of the angular resolution of the optical system, forming an image of the object, and additive noises on the reconstruction accuracy of the object surface shape using the proposed method.
