Paper Abstract

Neutron source images of a compressed DT target burn region were obtained in 1994 on the Phebus laser facility at CEL-V, by using a penumbral imaging technique. The symmetric biconical aperture generates a signal-dependent noise which degrades the spatial resolution of the system. The recorded image must be corrected for both instrumental effects and noise. Then by deconvolving from the point spread function of the aperture, we obtain the neutron source distribution. The information structure contained in the raw image and the reconstruction techniques used are explained. Practical and theoretical problems that need to be resolved, including the amount of information in the raw data, will be discussed. Also results and comparative evaluation of those methods are presented.
