ABSTRACT
Inertial confinement fusion is aimed at imploding a deuterium-tritium fuel pellet which is irradiated by a powerful laser light of the power 1 to 100 TW and pulse duration 0.1 to 10 nsec. According to the increase of the electron temperature, the ion becomes fully ionized and the bremsstrahlung radiation will exceed the recombination radiation. Since pinhole imaging requires high yield of the reaction products, various coded aperture imaging processes have been proposed to increase the solid angle of observation. When the interaction range becomes long due to the large plasma corona formation, the parametric instabilities appear to cause anomalous absorptions. The measurements of the laser fusion are performed using various types of measuring equipment surrounding the target on the one-shot basis, which makes it necessary to use data processing techniques.
