Fiber-optical Doppler anemometer |
摘要 |
In a fiber-optical Doppler anemometer for measurement of fluctuating light or the Doppler broadening of laser light scattered by a scattering medium, for example by particles in motion, coherent laser light is passed via a fiber-optical coupler (1) and a submerged fiber-optical probe (2) into the scattering medium, and the light scattered back by the scattering medium is picked up by the submerged fiber-optical probe (2), branched by the fiber-optical coupler (1) and passed to a photodetector (3).
