Description
Summary:The efficiency is investigated by computer simulations of a LIDAR-type approach for non-destructive single-sided gamma-ray probing and tomography of dense optically-opaque media. The approach is based on time-to-range resolved detection of the backscattering returns from the probed object (irradiated by pulsed gamma-photon beams) and determination of the internal distribution of the attenuation and Compton-backscattering coefficients. The image-reconstruction accuracy of sensing homogeneous and multifragment objects is investigated as a function of the depth of sensing. The results obtained show that this approach allows one to reliably establish the presence, the material content, and the disposition of different ingredients and flaws without noticeable influence of masking effects.
