Design of Near-field Coded Aperture Cameras for High-resolution Medical and Industrial Gamma-ray Imaging
Coded Aperture Imaging is a technique originally developed for X-ray astronomy, where typical imaging problems are characterized by far-field geometry and an object made of point sources distributed over a mainly dark background. These conditions provide, respectively, the basis of artifact-free and high Signal-to-Noise Ratio (SNR) imaging. When the coded apertures successful in far-field probl...
متن کاملImaging Analysis of the Hard X-ray Telescope ProtoEXIST2 and New Techniques for High Resolution Coded Aperture Telescopes
Wide-field (& 100 deg) hard X-ray coded-aperture telescopes with high angular resolution (. 2′) will enable a wide range of time domain astrophysics. For instance, transient sources such as gammaray bursts can be precisely localized without assistance of secondary focusing X-ray telescopes to enable rapid followup studies. On the other hand, high angular resolution in coded-aperture imaging int...

متن کاملSingle-shot Resolution of X-ray Monitor Using Coded Aperture Imaging
We report on tests of an x-ray beam size monitor based on coded aperture imaging[1]. This technique uses a mask pattern to modulate incoming photons, with the resulting image being deconvolved through the mask and detector responses, including the effects of diffraction and attenuation materials in the path, over the spectral and angular distribution of the synchrotron radiation generated by th...
متن کاملHigh-resolution Timing Observations of Spin-powered Pulsars with the Agile Gamma-ray Telescope
AGILE is a small gamma-ray astronomy satellite mission of the Italian Space Agency dedicated to high-energy astrophysics launched in 2007 April. Its ∼1 μs absolute time tagging capability coupled with a good sensitivity in the 30 MeV–30 GeV range, with simultaneous X-ray monitoring in the 18–60 keV band, makes it perfectly suited for the study of gamma-ray pulsars following up on the CGRO/EGRET...
