Numerical Simulation on PSF of Pinhole Imaging System for Fast Neutron

    Graphical Abstract
    • Abstract
  • The point spread function (PSF) of a pinhole imaging system for fast neutron has been studied through MonteCarlo method. The PSFs under different conditions have been obtained and analyzed by fitting the simulating data with Gauss function. As the results show， when the excursion is little， the PSF obtained by Gauss function fitting is feasible. A baffle will reduce the error and improve the spatial resolution remarkably.
