Abstract
A new, technique is proposed to reconstruct an astronomical image by using a phase retrieval from exponential filtered and unfiltered images based on the Fourier series expansion method. The amplitude of the Fourier transform of the filtered image is a mixture of the information of the Fourier amplitude and phase corresponding to the unfiltered image. Therefore, the phase information can be derived from the Fourier modulus of the filtered image based on the Fourier decomposition method. We have tried to apply this method to stellar speckle interferometry and the successful reconstruction of a double star image has been obtained.
