PROBLEM TO BE SOLVED: To provide a device for measuring temperature distribution capable of precisely detecting an object to be detected by calibrating the output characteristics of objective temperature of each element over a wide measuring temperature range. SOLUTION: The device is provided with a plurality of thermopile elements 121 for detecting the distribution of infrared ray, a lens 11 for condensing from the detection range and a temperature operator 25 for calculating the temperature from the detection signal. A calibration value memory 24 for storing the calibrated data obtained from three black body furnace temperature points is arranged in the device. The temperature operator 25 calculates the temperature from the detection signal by using the calibration data. COPYRIGHT: (C)2007,JPO&INPIT
