By the Numbers: Photon Counting and Number Resolution
May 1, 2023 — Light transmits information about its emitter (source) and the medium of propagation. If this information is relevant, the light can be detected for analysis — and it has been detected with increasing levels of sensitivity and resolution over the years. Today’s detectors have the ability to achieve single-photon resolution. Putting such capabilities into practical application is still not a trivial task, however, and can benefit from a deeper understanding of the principles of
Photonic Gas Analysis Probes Upgrades in Sources and Detectors
