| Outline of Final Research Achievements |
X-ray free electron lasers (XFELs) permit non-crystalline biological samples to be imaged with coherent diffraction imaging (CDI). The iterative computational methods, such as the hybrid input-output (HIO) algorithm, have been proposed to recover the phase information from the diffraction intensity. These methods are often unstable in the presence of noise and missing region in the diffraction pattern. We propose a protocol to reconstruct a reliable image of the sample. Numerical and experimental studies demonstrate the effectiveness of our method.
