A novel dual-energy fast neutron imaging technique is presented using short-pulse laser-
driven neutron sources to leverage their inherent adaptive spectral control to enable 3D
volume segmentation and reconstruction. Laser-accelerated ion beams incident onto
secondary targets create directional, broadband, MeV-class neutrons. Synthetic radiographs
are produced of multi-material objects using ion and neutron spectra derived from analytic
and numerical models. It is demonstrated that neutron images generated from small …
