Detection of free surface motion using a masked aperture technique

  • 1. Los Alamos National Laboratory, Los Alamos, New Mexico 87545

Description

A new noncontacting technique for measuring the arrival of a stress wave at the free surface of a very hot fluid metal has been developed. By use of an optical lever arm and a coded aperture, the new technique avoids the extreme sensitivity of optical interferometers, while allowing accurate measurement of rapid surface motions
