Abstract

To investigate the uniformity of compression of spherical targets irradiated with high-energy CO₂ lasers, an array of pinhole cameras has been set up to obtain 2-D views from four different directions. To reconstruct the 3-D source we have devised a computer code based on a maximum entropy algorithm. With synthetic input data the code gives acceptable reconstructions provided the source is smooth and has a simple shape. We present a set of serial slices through the reconstructed x-ray emission distribution in a glass microsphere imploded with the LASL two-beam CO₂ laser.
