Presentation for the SPIE Conference on High-Speed Photography and Photonics, Alexandria VA, September
20-24, 2004. Talk: Thursday 9/23, 11:30 am, Session 17, Interferometry and Imaging.
Interferometric techniques have been used routinely for more than 20 years to measure velocities of explosive
shock-fronts. Recently, structured-light measurements have been used for the same purpose. Explosions
accelerate surfaces to as much as 15 km/sec in a nanosecond or less, often generating much light, large changes
in reflectivity, and ejecting particles or layers at different speeds. I will describe the current performance of
fiber-optic displacement-interferometers, Fabret-Perot inteferometers, velocity interferometers (VISAR), and
structured light, in this interesting physical space.
