ABSTRACT:
An optical fiber temperature sensor employs a holey fiber. The holey fiber has an optical fiber concentrated part that a predetermined length of the holey fiber is concentrated in a spot region that is included in a space to be measured in temperature distribution. The optical fiber concentrated part has a bend formed by looping or winding the holey fiber.
