The incoherent imaging properties of ptychography are discussed in this paper. Usually a coherent light source is employed in ptychography for the recording of the diffraction patterns. However, in combination with a curved illumination it is possible to obtain an image quality of the reconstructed images that is equal to the one known from incoherent imaging. The underlying principle and results to demonstrate these findings are presented in this paper. Moreover, it will be shown that consequently not only the coherent speckle noise but likewise the resolution can be increased.
