A SURVEY OF OPTICAL INTERFEROMETRY AS APPLIED TO PLASMA DIAGNOSTICS,

Abstract

The principles and techniques involved in the application of optical interferometry to plasma studies are reviewed. The assumptions and accuracy of the theoretical calculations are summarized. Experiments to date in the field are reviewed, and recent experiments at Aerospace Corporation are described in which monochromatic interferograms about two-dimensional, sharp and blunted bodies have been obtained using an image converter camera and an exploding-wire light source. Resolution time down to 20 nanoseconds have been obtained while maintaining a conventional field of view. Using the multiple frames provided by the image-converter camera, the flow fields have been studied as a function of time. Whitelight color interferograms of these flows have also been obtained at exposure times of 50 nanoseconds using a recently developed Kerr cell. (Author)
