Abstract

Velocity interferomety has been used to determine velocities of miniature laser-driven flyer plates with sub-nanosecond (100 ps typical) time resolution. Since laser-driven flyer plates can have acceleration 101 0 m/s2 and attain 95 of terminal velocity within 20 nanoseconds the acceleration rate and terminal velocity cannot easily and accurately be resolved by current velocity interferometry techinques because of limitiations in temporal resolution of the interferometer and/or spatial resolution for conventional methods of recording raw data. By selecting an interferometer and recording system that is appropriate for the experiment sub-nanosecond time resolution is possible.
