Abstract: A method of collecting radiation information of a turbine blade, the method including: 1) collecting a radiated light from the surface of the turbine blade, analyzing the radiated light using a spectrometer to calculate compositions and corresponding concentrations of combustion gas; 2) calculating an absorption coefficient of the combustion gas at different concentrations; 3) calculating a total absorption rate of the combustion gas at different radiation wavelengths under different concentrations of component gases; 4) obtaining a relationship between the radiation and a wavelength; 5) finding at least 3 bands with a least gas absorption rate; 6) calculating a distance between a wavelength of a strongest radiation point of the turbine blade and the center wavelength, and selecting three central wavelengths closest to the wavelength with the strongest radiation; and 7) acquiring radiation data of the turbine blade in the windows obtained in 6).

Abstract: An infrared temperature-measurement probe, including: a probe housing; a reflector; and a reflector adjusting mechanism. The probe housing includes an inner wall, an outer wall, a cooling channel sandwiched between the inner wall and the outer wall, a chamber surrounded by the inner wall, and a light transmission hole communicating with the chamber. The reflector includes a mirror and a mirror frame. The reflector adjusting mechanism includes a motion controller, a drive coupling, and three control rods. The reflector and the three control rods are disposed in the chamber of the probe housing. The motion controller is disposed outside the chamber of the probe housing. The drive coupling is disposed between the motion controller and the three control rods, and the motion controller is adapted to move each of the three control rods via the drive coupling. The mirror is imbedded in and is supported by the mirror frame.
