Abstract

A coded source imaging (CSI) system has been developed and tested at the High Flux Isotope Reactor (HFIR) CG-1D beamline at Oak Ridge National Laboratory (ORNL). The goal of this system is to use magnification to improve resolution of the imaging system beyond the detector resolution. For this system, coded masks have been manufactured at 10 μm resolution with 9 μm thick Gd patterned on Si wafers, a system model base iterative reconstruction code developed, and experiments have been performed at resolutions of 200 μm, 100 μm, 50 μm, 20 μm, and 10 μm with the object place greater than 5.5m from the detector giving magnifications up to 25 times.
