Abstract
The phase retrieval method using an exponential filter based on Fourier series expansion is used in the reconstruction of phase objects from experimental far field intensities. The phase objects in this experiment lens and a circular aperture placed on the center of the lens. The object is illuminated by a la-are a converging and the complex amplitude function on the circular aperture is reconstructed from three far field ser beam, intensities, which are obtained with and without the exponential filter at the aperture. A cross section of the reconstructed phase is found to be almost the same as that of the theoretical phase at the aperture.
