ABSTRACT
Zernike phase contrast microscopy is a well-established method for imaging specimens with low absorption contrast. It has been successfully implemented in full-field using visible light and X-rays. In Cowley's reciprocity principle connects scanning imaging. Even though the discussed by several authors over past thirty years, only recently it was experimentally verified X-ray microscopy. this paper, we investigate image formation particular detailed focus on origin of artifacts that are typically associated We demonstrate X-rays effect mask design halo present an optimized respect to photon efficiency artifact reduction. Similarly, due observations conclusions work have direct applicability as well.
