Description
Scintillation detectors are widely used in high-energy physics experiments. 3D position sensitivity of these detectors can significantly expand their applications. Inspired by plenoptic cameras, we designed a prototype system optimized for optical imaging under photon-limited conditions. We calibrated the system using a tunable light source at precisely controlled positions. The resulting images were denoised and downsampled to generate simulated photon-limited measurements. We demonstrate that both single-site and double-site events with O(100) detected photons can be reconstructed in 3D with millimeter-scale position accuracy. In this talk, I will discuss the system’s design, construction, calibration, and performance.
