Quantitative Phase and Absorption Contrast Imaging

We present an algorithm for coherent diffractive imaging with phaseless measurements. It treats the forward model as a combination of and incoherent waves. The reconstructs absorption phase contrast that quantifies attenuation refraction waves propagating through object. requires or partially illuminations, several detectors to record intensity distorted wave passes object under inspection. diversity obtained by putting masks between source object, provides enough information imaging. computational cost our is linear in number pixels image. Therefore, it efficient high-resolution Our guarantees exact recovery if image sparse given basis. Numerical experiments setting diffraction objects validate efficiency precision suggested algorithm.
