The multibeam Fabry-Perot velocimeter: Efficient measurement of high velocities

Journal Article · · Science and Technology Review
OSTI ID:376816
In support of the Laboratory`s scientific stockpile stewardship mission, we have developed a multibeam Fabry-Perot velocimetry system to more efficiently measure continuous velocities during our experiments. These data are invaluable for testing the adequacy of our hydrodynamic computer modeling codes. A new fiber optic system and Laboratory-designed optical devices allow us to obtain five or even ten continuous velocity records from an experiment using just one Fabry-Perot interferometer. Before the advent of this system, we could obtain only one record per interferometer. We have also developed a dual-cavity interferometer that greatly facilitates reading the interference fringes recorded during our experiments.
