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.

Abstract: An apparatus for measuring temperature of turbine blades, including: a radiation collection device, a data processing module; a master control unit (MCU); a calibration module; and a motion servo. The radiation collection device includes a scan reflector, a collimator lens, a first dichroic mirror, a first focus lens, a visible and near-infrared (VNIR) detector, a second dichroic mirror, a second focus lens, a short-wave infrared (SWIR) detector, a third focus lens, and a medium-wave infrared (MWIR) detector. The calibration module includes a calibration reflection mirror and a blackbody furnace. The scan reflector, the collimator lens, the first dichroic mirror, the second dichroic mirror, the third focus lens, and the MWIR detector are disposed successively along a first optical axis; the first dichroic mirror, the first focus lens, and the VNIR detector are disposed successively along a second optical axis that is perpendicular to the first optical axis.
