Abstract

Abstract

The coded source can increase the neutron flux while keep good beam collimation in neutron imaging. A computer simulation method for modified uniformly redundant arrays coded neutron source imaging was established and the optical experiments were carried out subsequently. The results indicate that the image can be reconstructed well by the correlation algorithm in coded source imaging. The dimension and resolution of the reconstructed objects are similar with those acquired by single pinhole, and the exposure time is shortened greatly. The impact of non-ideal conditions on image quality was also explored. If the object is placed in a position with magnifying and rotating deviations from ideal conditions, the projection can not match the CCD pixels of the detector and the decoding array, wh
