Single-Pixel Photon-Counting Imaging Based on Dual-Comb Interferometry
Nanomaterials, 2021 We propose and experimentally demonstrate single-pixel photon counting imaging based on dual-comb interferometry at 1550 nm. Different from traditional dual-comb imaging, this approach enables imaging at the photon-counting regime by using single-photon ...

Photon counting Detectors: Concept, technical Challenges, and clinical outlook.
European Journal of Radiology, 2022 Photon counting detectors in Computed Tomography overcome several drawbacks of classical detectors used in Computed Tomography. Classical detectors measure X-rays by converting them into visible light during the initial absorption inside a pixel ...
