摘要：

A novel single-phase-grating Phase contrast system was simulated using Sommerfield-Rayleigh diffraction integrals. We accomplish in one X-ray optic the functionality that requires 2-3 optics in Miao et al Nature Physics 2015. We retain all their benefits of not requiring the absorption grating (analyzer) in Talbot-Lau interferometers. This will reduce the dose-requirement (approximately by a factor of two). We observed interference pattern (pitch 0.2mm) with grating to detector distance of 50mm for parallel beam source. The interference pattern can be tuned to different applications depending on detector resolution. Our eventual goal is to achieve compact interferometry of the design lengths required for a clinical mammogram system.
