A demonstration of the ability of digital holography to image and to measure spatial variations of the polarisation of an object wave with a single image acquisition is presented. This is achieved by recording a hologram with two reference beams presenting ...
Off-axis holograms recorded with a CCD camera are numerically reconstructed with a calculation of scalar diffraction in the Fresnel approximation. We show that the zero order of diffraction and the twin image can be digitally eliminated by means of filteri ...
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 perfo ...
