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.
