PCT No. PCT/US85/00295 Sec. 371 Date Sep. 13, 1985 Sec. 102(e) Date Sep. 13, 1985 PCT Filed Feb. 25, 1985 PCT Pub. No. WO85/03855 PCT Pub. Date Sep. 12, 1985.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 area. The device also has utility in industrial applications.
