Multiplying the number of effective channels in time-domain single-photon counting applications

This study investigates the possibility of exploiting the time-tagging modality and high throughput of modern time-correlated single-photon counting electronics to convey the signal from multiple detectors to the same time-to-digital converter (TDC) channel, effectively reducing the costs and complexity of time-resolved spectroscopy systems. This approach provides the capability of employing a large number of detectors, laying the groundwork for developing sophisticated multichannel systems capable of managing up to more than 100. detectors, significantly enhancing photon-counting capabilities, and paving the way for future advancements in the field.
