Description
X-ray phase contrast imaging (XPCI) is a cutting-edge diagnostic technique based on the phase shift of x-ray photons induced by a density gradient. By enhancing contrast through refraction and diffraction at material interfaces and density gradients, XPCI is particularly well-suited for imaging laser-driven shock propagation inside targets. In this work, we advanced the platform originally developed by L. Antonelli et al [EPL 125, 35002 (2019)] at the GSI PHELIX laser facility. We have compared different X-ray sources and geometries to optimize the backlighter performance. Results demonstrate high-quality imaging of shock waves propagating through planar plastic and foam targets. We will also discuss the next step of extending this platform toward direct imaging of early-time, laser-imprinted perturbations.
