Computer analysis of two-dimensional images in the Zernike phase contrast method for hard X rays

Computer analysis of two-dimensional images in the Zernike phase contrast method for hard X rays Abstract The problems of the numerical simulation of two-dimensional images in the Zernike phase contrast method in hard X rays are analyzed. Calculations are performed for experimental conditions typical of third-generation synchrotron radiation sources (ESRF, APS, Spring-8, etc.). Schemes are considered where the focusing elements are a refracting lens and a zone plate and the phase-shifting element is situated at the point of the source image. It is shown that the refracting lens allows better resolution than the zone plate. A technique similar to ptychography can be successfully applied to improve the quality of the images obtained by the Zernike phase contrast method. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract The problems of the numerical simulation of two-dimensional images in the Zernike phase contrast method in hard X rays are analyzed. Calculations are performed for experimental conditions typical of third-generation synchrotron radiation sources (ESRF, APS, Spring-8, etc.). Schemes are considered where the focusing elements are a refracting lens and a zone plate and the phase-shifting element is situated at the point of the source image. It is shown that the refracting lens allows better resolution than the zone plate. A technique similar to ptychography can be successfully applied to improve the quality of the images obtained by the Zernike phase contrast method.
