Determination of Angle of Refraction in X-Ray Phase-Contrast Imaging Using Geometric Optics Method

Photonics
The accurate calculation of the angle of refraction of X-rays passing through an object is essential in X-ray phase-contrast imaging. While the wave optics-based method is commonly employed to calculate the angle of refraction, it presents several ...

Diffractive And Refractive X-Ray Optics

AIP Conference Proceedings, 2004
We present a variety of diffractive and refractive x‐ray optics developed for imaging and microfocusing applications at synchrotron beam lines covering almost three orders of magnitude in photon energy from the EUV to hard x‐rays. For EUV radiation, soft x‐rays and the multi‐keV region, we have fabricated and tested Fresnel zone plates providing high ...

Simulating X-ray telescopes with McXtrace: A case study of ATHENA's optics [PDF]

, 2016
We use the X-ray ray-tracing package McXtrace to simulate the performance of X-ray telescopes based on Silicon Pore Optics (SPO) technologies. We use as reference the design of the optics of the planned X-ray mission Advanced Telescope for High ENergy ...
