Progress in the development of tomographic information-processing methods for application to ICF target characterization

A precise and accurate knowledge of the charactistics of three-dimensional micro-objects such as inertial confinement fusion (ICF) targets and laser-p roduced plasmas is required to analyze the results of laser fusion experime nts. Significant advances have been made in the development of tomographic information-processing methods for application to ICF target characterizati on. Topics discussed include (a) new high-resolution algorithm obtained by symmetrizing a basic filtered back projection algorithm, ib) algorithms for threshold target characterization, (c) new approach to micro-object scannn ing based on quasi-uniform geometry, (d) ICF target preparation for tomogra phic characterization.
