A broad spectrum of applications has emerged for phase retrieval, including image reconstruction from stellar interferometer data, coherent lensless imaging, wavefront sensing for adaptive optics and aligning telescopes, and optical metrology. In this talk, we will focus on the application of these algorithms to the x-ray regime. We will describe a new coherent lensless imaging approach which allows a direct image reconstruction using the boundary-wave diffracted from a sharp feature as a holographic-like reference wave. We will also discuss the application of phase retrieval with transverse translation diversity as an image reconstruction technique and a novel approach for x-ray beam measurement.
