Abstract

A new technique to measure the refractive index of shocked materials is reported. The arrival of a transparent shock at the free surface of an optical window generates a discontinuity in the observed interferometry record. In this work, we show that the magnitude of that discontinuity is simply defined by the shock velocity, the shocked refractive, and the free-surface velocity. This new technique, to measure the high-pressure refractive index of a transparent material, is demonstrated.
