Abstract
The system is based on combined detector: scintillating plate+image intensifier+CCD matrix. The sensitivity of the detector allows the detection of single photon with energy higher than 60 keV. The hexagonal URA masks of ranks 6 and 9 are used for coded mask imaging; transparent elements of mask are cylindrical holes of diameter 1.3–2.2 mm). The imaging possibilities of device are presented by images of point and circular objects of different diameters obtained in experiments.
