Three-dimensional imaging of laser-imploded targets using X-ray computed tomography technique

An X-ray emission computed tomography technique has been demonstrated to diagnose the laser implosion uniformity of spherical targets. Three-dimensional images of a compressed core were reconstructed from five pinhole camera images obtained at different viewing directions by using an iterative algorithm. The uniformity of the heated plasma is estimated from the intensity distribution of the X-ray emitted from the surface of the target.
