We performed miniature flyer impact experiments to investigate the thermodynamic and optical properties of shocked single-crystal pentaerythritol tetranitrate (PETN). A thin metal plate was accelerated by irradiating it with pulse from a tabletop laser, and impacted on a single crystal of PETN along the  axis. The particle velocity history of the laser-accelerated flyer was measured using an optically recording velocity interferometer system. The relationship between the actual particle velocity and the particle velocity measured by the velocity interferometer was obtained by analyzing the particle velocities immediately before and after the flyer collided with the PETN  single crystal. The change in the refractive index of the shocked PETN  immediately after a shock wave had propagated was also studied.
