Researchers just created the world's first image of a terrestrial gamma-ray burst, one of the most mysterious and energetic events on Earth.
This paper introduces a new method, named radiation periodic integration measurement (RPIM), to improve the imaging speed and quality in the scan radiography without the interference of circuit RC time constant. However, the integral period may sometimes be different from the sampling period in ...

The lack of energy resolution associated with Cherenkov detectors impedes fine-resolution imaging in certain applications, when various energies of gamma-rays are used to extract information about the object, but can be improved with careful image reconstruction. In this work, we evaluate the performan...
Reconstruction of multiplex images produced by coded‐aperture telescopes for extended sources of radiation which cannot be reflected or refracted (moderate‐ to high‐energy x rays and low‐energy γ rays) can be accomplished by least‐squares solution of an overdetermined set of simultaneous equations...
