FLUID FLOW SENSING APPARATUS FOR IN VIVO AND INDUSTRIAL APPLICATIONS EMLOYING NOVEL DIFFERENTIAL OPTICAL FIBER PRESSURE SENSORS |
摘要 |
An optical fiber fluid flow device is provided for in vivo determination of blood flow in arteries. The device includes a fiber optical fluid pressure measuring device having at least first and second optical fiber sensors which optical fiber sensors are positioned in the blood passage and in a restricted flow area in the blood passage and the two fiber optical pressure fluid sensors are connected to an interferometer associated with an opto-electronic demodulator which has an output signal representing the differential pressure between the two sensed areas. The device also has utility in industrial applications. |
