Abstract

The Fabry-Perot laser velocimeter is used at LLNL for hydrodynamic, equation-of-state, surface-ejecta mass measurements and for other applications. Velocities of shocked surfaces can be measured to better than 1%, and multiple records can be superimposed on a single piece of film. Many phenomena are being investigated for possible sources of error. One concern was whether the direction of the surface normal could affect the measured Doppler shift, or whether the direction of the particle velocity was sufficient to determine the shift. A series of experiments with angles between the laser and particle velocity as small as 20° have shown that for the surface smoothnesses that we encounter, we see no effect caused by varying the direction of the surface normal.
