Use of the Multiple-Beam Interferometry in Measurement of Shells for Laser Fusion Targets

Abstract

AbstractIn selection of shells for laser fusion targets, measurement of the wall nonuniformity with an accuracy better then 100 Å is needed. With this aim, the possibility of using multiplebeam interferometry for shell inspection has been investigated. Technical approaches have been found which have made possible the advantages of multiple-beam interferometry. For one of methods, bases on the multiple-beam interference used to process oscillograms, the sensitivity of 20 Å has been obtained in the wall nonuniformity measurements.
