Single-shot surface 3-D imaging by optical coherence factor (Conference Presentation)
Paper Abstract
We report a single-shot surface three-dimensional (3-D) imaging method that uses optical coherence as a contrast mechanism to acquire the vertical (z-direction) information of an object. The illumination of the imaging system comes from a light source with the optical coherence length similar to the depth of field (DoF) of the optical system. Holographic recording is used to retrieve the coherence visibility factor, which is then converted to z-direction information. In the experiment, we compare the imaging results of our method to conventional incoherent imaging results, showing that this contrast mechanism is able to provide additional information. We also validate our 3D imaging results by using axial scanning full-field optical coherence tomography.
