title = "Three-dimensional shape measurement by means of depth-to-coherence coding of the object shape",
abstract = "In this contribution, we present a novel approach for three-dimensional (3D) mapping that is based in the coding provided by the coherence length of a laser source over the object depth. By using a classical temporal electronic speckle pattern interferometric (T-ESPI) setup, the object depth is encoded into the amplitude of the interference pattern instead of in the phase distribution. After performing phase-shifting method, the object shape is recovered by means of a range image obtained by computing the visibility of the image set of interferograms and where each gray level is representative of a given object depth. Experimental results validate the proposed approach for reflective diffuse objects at different measurement distances.",
