Summary
This article highlights a novel approach where a tailor-made double-tapered optical fibre array is integrated with a scintillator, enabling flexible and high-performance radiation detectors with improved light collection and spatial resolution compared to existing technologies. This design overcomes limitations of traditional pixelated scintillators by guiding scintillation light via evanescent wave coupling into the fibres and leveraging photon recycling within the scintillator. The resulting device demonstrates a high light yield, state-of-the-art spatial resolution, and mechanical flexibility, opening new possibilities for applications like flexible detectors in cone-beam CT systems.
