Modelling of Phase Contrast Imaging with X-ray Wavefront Sensor and Partial Coherence Beams. [PDF]
Sensors (Basel), 2020 The Hartmann wavefront sensor is able to measure, separately and in absolute, the real δ and imaginary part β of the X-ray refractive index. While combined with tomographic setup, the Hartman sensor opens many interesting opportunities behind the direct ...

Recovery of undamaged electron-density maps in the presence of damage-induced partial coherence in single-particle imaging. [PDF]
IUCrJ, 2020 Resolving the electronic structure of single biological molecules in their native state was among the primary motivations behind X-ray free-electron lasers. The ultra-short pulses they produce can outrun the atomic motion induced by radiation damage, but

Partial Recovery of Coherence Loss in Coherence-Assisted Transformation
Entropy, 2023 Coherence-assisted transformation under incoherent operations is discussed. For transformation from the pure state to the mixed state, we show that the coherence loss can be partially recovered by adding auxiliary coherent states.

Linear algebraic theory of partial coherence: discrete fields and measures of partial coherence [PDF]
Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2002 A linear algebraic theory of partial coherence is presented that allows precise mathematical definitions of concepts such as coherence and incoherence. This not only provides new perspectives and insights but also allows us to employ the conceptual and algebraic tools of linear algebra in applications. We define several scalar measures of the degree of

Linear algebraic theory of partial coherence: continuous fields and measures of partial coherence [PDF]
Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2016 This work presents a linear algebraic theory of partial coherence for optical fields of continuous variables. This approach facilitates use of linear algebraic techniques and makes it possible to precisely define the concepts of incoherence and coherence in a mathematical way.
