Device and system for detecting blood vessel based on fiber optic probe method for manufacturing the device and method for detecting blood vessel using the system

摘要

The present invention relates to a blood vessel measuring device using a Doppler interferometer and an optical fiber. More specifically, the present invention relates to a blood vessel measuring device which Fourier transforms an optical signal received through the optical fiber forming a curved surface and the Doppler interferometer, and can quantify a position of the blood vessel and a flow speed of a bloodstream with a phase value obtained by the Fourier transformation. The blood vessel measuring device comprises: the Doppler interferometer including a light source, a circulator which guides light irradiated from the light source and reflective light reflected from a subject in one direction and a detection part; the optical fiber having one end connected to the circulator; and a spacer having one end coupled to the other end of the optical fiber.
