Coded-aperture imaging is a well-established and widely applied concept of optics. For the case of radiation detection, there has been a particular focus on the development of X-ray and gamma-ray imaging systems. In recent years, however, coded-aperture based neutron imaging has also seen increased attention. The main advantage of coded-aperture imaging is the increased signal-to-noise-ratio (SNR), when compared to single opening pinhole devices. This research project considers relatively small scale coded apertures. When complemented by a suitably sized sensitive organic detector, such a system could be packaged into a portable device for nuclear decommissioning applications.
