To improve imaging performance of photo-neutron explosive detection system
reasons of spatial resolution deterioration is investigated
and physical and mathematical model are established.The function is solved using iterative algorithm under constraints and non-constraints condition
respectively.The simulation and experiment results show that the method with constraints can improve effectively accuracy of the explosives detection system by eliminating the pixel overlapping.
