Abstract
Laboratory experiments have been performed to demonstrate the capabilities of a γ-ray imaging system employing a NaI Anger camera and a rotating coded aperture mask. The mask incorporates in its design a new type of hexagonal uniformly redundant array (HURA) which is essentially antisymmetric under 60° rotation. The image formation techniques are described and results are presented that demonstrate the imaging capability of the system for individual and multiple point sources of γ-ray emission. The results are cornpared to analytical predictions for the imaging and point source localization capabilities of coded aperture systems using continuous detectors.
