Abstract
Abstract

The X-ray Talbot–Lau interferometer is a sensitive method for probing wavefront phase distribution and high-energy-density plasmas. In this study, we have quantitatively calculated the fringe visibility obtained using an X-ray cascaded Talbot–Lau interferometer (CTLI) with W-absorption gratings of different structural heights. A cascaded configuration with different W-absorption gratings was built experimentally to verify the validity of the calculation results. The relationship between the sensitivity of the interferometers and the duty ratio of the gratings is also discussed. The analytical results presented in this study will be useful for optimizing the design and fabrication of W-absorption gratings to improve the sensitivity of X-ray CTLI.
