| 3 | An efficient method for unfolding kinetic pressure driven VISAR data显示文摘Velocity Interferometer System for Any Reflector(VISAR) [Barker and Hollenbach, J. Appl. Phys. 43, 4669(1972)]is a well-known diagnostic that is employed on many shock physics and pulsed-power experiments. With the VISAR diagnostic, the velocity on the surface of any metal flyer can be found. For most experiments employing VISAR, either a kinetic pressure [Grady, Mech. Mater. 29, 181(1998)] or a magnetic pressure [Lemke et al., Intl J. Impact Eng. 38,480(2011)] drives the motion of the flyer. Moreover, reliable prediction of the time-dependent pressure is often a critical component to understanding the physics of these experiments. Although VISAR can provide a precise measurement of a flyer's surface velocity, the real challenge of this diagnostic implementation is using this velocity to unfold the timedependent pressure. The purpose of this paper is to elucidate a new method for quickly and reliably unfolding VISAR data. | M.Hess K.Peterson A.Harvey-Thompson | 2015 | High Power Laser Science and Engineering2015，3，3： | 0 |
