Description
High-spatial resolution scintillator detectors can achieve very precise particle tracking capability, when owing to a segmentation of a few hundred micrometer.
However, the required granularity comes with the price of additional complexity in the detector manufacturing and construction as well as in the huge number of readout channels, when scaling up to large-volume systems.
In arXiv:2511.09442, we proposed the PLATON concept, a change of paradigm that consists of combining the concept of plenoptic imaging with Single-Photon Avalanche Diode (SPAD) array imaging sensors to obtain 3D images of particle interactions in an unsegmented monolithic volume of scintillator.
Applications can range from neutrino detection to particle calorimetry.
In this talk we present the first-ever built plenoptic camera instrumented with a SPAD array sensor as well as newly developed analytical and artificial intelligence-based 3D imaging techniques.
The performance achieved in imaging $^{90}$Sr electron as well as two-photon absorption laser events in plastic scintillator will be reported.
Finally, the case study of accelerator neutrino detection with a realistic optical simulation, including the scalability of this technology to the tonne-scale, will demonstrate the unique potential of this novel technology, with a spatial resolution down to a few hundred micrometres.
