X 射线相衬成像 (XPCI) 是一种多功能技术，可应用于许多领域，包括基础物理、生物学和医学。当 X 射线吸收射线照相需要高密度比才能有效成像时，XPCI 的图像对比度是密度梯度的函数。在这封信中，我们将 XPCI 应用于激光驱动冲击波的研究。我们的实验是在 GSI 的拍瓦高能重离子实验激光器 (PHELIX) 上进行的。使用两束激光：一束激光束发射冲击波，另一束激光束产生用于相衬成像的 X 射线源。我们的结果表明，该技术适用于热致密物质（WDM）、惯性约束聚变（ICF）和实验室天体物理学的研究。版权所有 (C) EPLA，2019
X-ray phase-contrast imaging (XPCI) is a versatile technique with applications in many fields, including fundamental physics, biology and medicine. Where X-ray absorption radiography requires high density ratios for effective imaging, the image contrast for XPCI is a function of the density gradient. In this letter, we apply XPCI to the study of laser-driven shock waves. Our experiment was conducted at the Petawatt High-Energy Laser for Heavy Ion EXperiments (PHELIX) at GSI. Two laser beams were used: one to launch a shock wave and the other to generate an X-ray source for phase-contrast imaging. Our results suggest that this technique is suitable for the study of warm dense matter (WDM), inertial confinement fusion (ICF) and laboratory astrophysics. Copyright (C) EPLA, 2019
