Nanophotonic scintillators for high-energy particles detection, imaging, and spectroscopy

An imaging setup comprising:

• a high energy particle (HEP) source emitting HEP of various energies;
• a scintillating device, comprising a plurality of stacked subregions, such that different energies penetrate to different depths within the stacked subregions;
• and wherein each subregion comprises a patterned surface and scintillates at a specific frequency, angle and polarization;
• a detector to receive emissions from each stacked subregion;
• and
• a reconstruction algorithm to determine an original energy distribution based on a scintillation pattern received from the plurality of stacked subregions, wherein the scintillation pattern is optimally sparse for some transform.
