Optical tomography by means of a numerical low-coherence holographic technique
1997
Digital holograms are recorded by a CCD camera and are numerically reconstructed, in intensity and phase, by means of an algorithm which calculates their discrete Fresnel transform. By using a low-coherence source, the tomography of a 3D scene can be performed without lateral scanning with a depth resolution equal to the coherence length and a lateral resolution equal to the diffraction limit of the microscope objective used
