Subpixel Sensing for Charge-Sharing Events in Pixelated CdZnTe Detectors

Pixelated CdZnTe detectors mymargin have achieved excellent spectroscopic performance and showed the advanced capability of coded-aperture and Compton imaging. Subpixel sensing is a technique to improve their imaging capabilities. For single-pixel-triggered events, subpixel sensing was demonstrated years ago. This article proposes a method to calculate subpixel location for two-pixel-triggered charge-sharing events.
