Summary[edit]

Description

A low intensity beam of monochromatic light, emitted from a laser diode inside a BLF21-Series flowmeter travels via the probe’s fiber optic light guide through the probe head to illuminate the tissue under study. There, the laser beam is scattered by reflective components within the tissue. A portion of the light is reflected back, via the probe’s receiving fiber optic light guide, onto a photo detector inside the flowmeter. Generally, this received light has been reflected many times by stationary structures within the tissue as well as by one or more moving particles (mainly red blood cells) within the tissue. It is the moving Doppler effect
