Title OPTICAL FIBER SENSOR AND MEASURING DEVICE USING THE SAME
Abstract There are provided an optical fiber sensor enabling easy detection of an external world state and a measuring device using the same. An optical fiber portion (20a) for transmitting light has a tip end to which a hetero core portion having a different diameter than the core of the optical fiber portion (20a) is melted/adhered, thereby constituting a tip type optical fiber sensor (9) having a sensor portion (4) formed by the hetero core portion at the tip end. A light source (1) is connected to the end of the optical fiber portion (20a) of the tip type optical fiber sensor (9). The light coming into the optical fiber portion (20a) from the light source (1) and subjected to interaction with a measurement medium MD in the sensor portion (4) becomes a return light which is branched by an optical fiber coupler (2) and made to receive the light by a photodiode or a spectrum analyzer (6), thereby constituting an optical fiber sensor measuring device (100).
