Superconducting nanowire single-photon detectors: Next big thing in blood flow measurement

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate measurements. Now, researchers have developed a superconducting nanowire single-photon detector (SNSPD) — based DCS device with a high signal-to-noise ratio and high sensitivity for blood flow.
