ABSTRACT:
A radiation thermometer has a detector for receiving radiation energy from a target object, and the detector generates an AC signal as a result of movement of a chopper. The AC signal is rectified by a rectifying circuit and the rectified signal is supplied to a microcomputer. On the other hand, temperatures around the detector are detected by a temperature sensor and the temperature of the target object is measured based on those detected values. In addition, the radiation thermometer has various calibration modes other than a measurement mode. In a calibration mode I, calibration data concerning a difference in characteristics of the temperature sensor for each thermometer is obtained. Data for correcting timing for synchronous rectification by the rectifying circuit is obtained in a calibration mode II. Calibration data for calculation of the temperature of the target object is obtained in a calibration mode III. Those calibration data are temporarily stored in a non-volatile RAM so that the temperature of the target object can be calculated by using those calibration data when the measurement mode is selected.
