Fiber-type Laser Doppler Velocimeter using lensed Thermally-diffused Expanded Core fiber for liquid flow measurement

摘要

Fiber-type Laser Doppler Velocimeter (LDV) is a new type of downsized and low cost LDV with high precision measurement comparing with the conventional type LDV. We propose the use of fiber-type LDV using lensed Thermally-diffused Expanded Core (TEC) fiber for velocity measurement of liquid flow.
