Abstract
This paper reports on the imaging of a phase object using a differentiation filter. The differentiation filter consists of a photographic recording on a film where the amplitude transmittance changes gradually in a continuous manner. The filter is placed in the Fourier plane of a lens, and the differentiation image is taken by a CCD camera. This technique is applicable for objects with wide range of phase variations. A computer was used for image integration and to construct the 3D image. We have presented experimental results for a wedged phase object.
