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.
