Three-dimensional imaging of laser imploded targets

Abstract
An x-ray emission computed tomographic technique has been demonstrated to diagnose the laser implosion uniformity of spherical targets. Three-dimensional images of compressed core were reconstructed from five pinhole camera images obtained at different viewing directions by using an iterative algorithm. Good agreement between the experimental results and two-dimensional hydrodynamic simulations showed that the uniformity of initial target shell thickness has a significant influence on implosion symmetry.
