Abstract A high efficiency simulation method for propagation-based phase-contrast imaging, called directional macro-wavefront (DMWF), is developed with the aim of simulating high-energy phase-contrast imaging. This method takes both Monte Carlo and w

Polarized x rays or gamma rays generated from inverse Compton scattering (ICS) sources are high-brightness, quasimonochromatic, and polarization-tunable and are widely applied in medical imaging, material science, and nuclear physics research. In thi

High-energy charged particle radiography has been used for diagnostics of high-energy density matter, and electrons can serve as a promising radiographic probe that acts as a complement to commonly used proton probes. Here we report on an electron ra

The measurement of electron bunch temporal profile is one of the key diagnostics in accelerators, especially for ultrashort bunches. The electro-optic (EO) technique enables the precise longitudinal characterization of bunch electric field in a singl

Due to its small spot size, a Thomson-scattering X-ray source can produce high spatial coherent X-ray pulse, which is the prerequisite for phase-contrast imaging. In this paper, we will introduce the recent progress of phase-contrast imaging at Tsing

By acquiring compressed information directly, the compressed sensing theory provides a method to reconstruct signals from few sampled data. Based on this theory, a microwave imaging simulation system working at K-band frequencies (18-26.5GHz) was des
