Coded aperture imaging of gamma-rays using multiple pinhole arrays and multiwire proportional chamber detector
Abstract
Coded shadows of gamma-ray distributions are made using both random pinhole and nonredundant pinhole coded apertures with a multiwire proportional chamber as detector. Image reconstruction is done optically with incoherent light. Lateral and depth resoltuion results are presented and calculations of background and signal to noise ratios for the nonredundant aperture are made and compared with the single pinhole collimator.
