18 January 1977 Pulsed Laser Stereo Photography Of Electrically Exploded Bridges
Author Affiliations +
A technique is described for obtaining short exposure (≈8 ns) high resolution photomicrographs of electrically exploded bridges using a pulsed laser for bridge illumination and band-pass filters to eliminate the intense self light. Two cameras are described, one for a small field of view (til mm) and one for a relatively large field of view (≈20 mm). A carbon disulfide cell and a fiber-optic light guide are used to essentially eliminate speckle, which normally limits the resolution of laser photographs of diffuse surfaces. A series of photomicrographs showing the detailed burst characteristics of both flat and round bridges are shown.
