Abstract
A method of measuring temperature including the steps of calibrating a sensor disposed near one end of an optical fiber, the sensor having a source of light which irradiates light, the optical fiber being positioned at one end to receive light from the source of light; a transducer positioned near the other end of the optical fiber, the transducer being made up of at least two polymers that have refractive indices with different temperature dependencies and form a microphase separation structure; a reflection element for reflecting the irradiated light; and an arithmetic processing unit which receives the reflected light by exposing the sensor to two or more sources of heat whose values are known; and exposing the sensor to the portion whose temperature is to be measured.
