TEMPERATURE MEASURING APPARATUS

PROBLEM TO BE SOLVED: To measure the temperature on the surface of intricate shape, e.g. a human body, easily at a relatively narrow interval. SOLUTION: The temperature measuring apparatus comprises a detecting section 10 having detecting points distributed twodimensionally at the measuring points T of an object arranged at a distance shorter than the distance between detecting points S of a single optical fiber 1 arranged at a predetermined interval, a light emitting part 21 for delivering an optical signal from one end of the optical fiber 1, a light receiving section 24 for receiving a scattering light generated due to temperature difference at the detecting points S of the optical fiber 1, and a section 25 for operating the temperature at the detecting point based on an optical signal received at the light receiving section 24.
