Abstract :
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 orthogonal polarisations and different propagation directions. A CCD camera is used to record the hologram and the reconstruction is performed numerically
