発明の名称 (英語) TEMPERATURE SENSOR
発明の概要(英語) Provided is a temperature sensor capable of performing a highly reliable detection of temperature fluctuations. The temperature sensor comprises a light source unit for emitting a laser light, a separating unit for separating the laser light emitted from the light source unit, into a test light and a reference light, a sensing unit for arranging the optical path of the test light across a measured space, the temperature of which is measured, and a detecting unit for detecting the change in the temperature by causing the test light having crossed the measured space and the reference light thereby to detect the fluctuations of the interfering state. The sensing unit is disposed at the leading end of a cylindrical casing parallel to the optical path of the test light, and the separating unit is disposed at the root end of the casing. The casing is equipped at its leading end with a leading end wall having a transparent member for transmitting the test light, so that the test light having passed the transparent member may reach the sensing unit, and the leading end wall is equipped with a reflecting member for reflecting the reference light.
