Abstract: PROBLEM TO BE SOLVED: To provide an inspection system by which a face to be inspected can be inspected in a short time, with good efficiency and in a noncontact manner toy a continuous scanning operation without damaging and contaminating an object to be inspected and which can be applied even when the coating layer of the object to be inspected is thin. SOLUTION: A means by which the surface of an object to be inspected is irradiated with a laser beam is provided. A means wherein infrared rays radiated by a spot which is irradiated with the laser beam and which is heated are received so as to be input to an infrared radiation thermometer is provided. A scanning means wherein a sensor member on which the irradiation part of the laser beam and an infrared receiving part are arranged is scanned with reference to the surface of the object to be inspected is provided. A means by which the detected value of the infrared radiation thermometer is compared with standard data and by which the state of the coating layer of the object to be inspected is analyzed is provided.

Abstract: PURPOSE: To provide a fluid passage inspection method by which a structure with a fluid passage formed therein can be easily inspected for constrictions, blockage, etc., in the fluid passage from the outside of the structure using a radiation thermometer with high accuracy. CONSTITUTION: A subject 1 for inspection, with a fluid passage 5 formed therein, is put on a turntable 2, and after the subject for inspection is made to have a uniform temperature throughout by introducing cooling water of a fixed temperature into the fluid passage from the outside, hot water of a fixed temperature is introduced. As the subject 1 for inspection is rotated with the fluid passage 5 filled with the hot water, the temperature distribution of its outer surface is measured using a radiation thermometer 22 so as to measure the temperature of the overall periphery and to determine the positions of defects in the fluid passage based on positions where local low-temperature portions exist.
