Work of Yifeng Shao highlighted story in SPIE newsroom

Reconstructing the phase of a field from intensity measurements is a long-standing and ubiquitous challenge, known as the phase retrieval problem. The new phase reconstruction method by Yifeng Shao, PhD student @ImPhys, overcomes several challenges of conventional iterative CDI algorithms and holographic methods.

Last week his work was reported as a highlighted story in SPIE newsroom. The original paper was also published on Advanced Photonics in the first volume the first issue, which is a kind of honour. 

This method overcomes several challenges of conventional iterative CDI algorithms and holographic methods. It is particularly beneficial for achieving a large field of view when using a low degree of spatial coherence illumination. The researchers demonstrated that the method can be used to calibrate the mutual coherence function of an arbitrary partially spatially coherent beam, and expect that it can be applied to a wide range of wavelengths, from x-rays to infrared light, due to its wavelength independence.
