The accurate measurement of turbine blade surface temperature is crucial for ensuring the safe and stable operation of an aeroengine, as it can prevent overheating and damage to the blades, extend the engine′s lifes-pan, and ensure the aircraft′s safe flight. Non-contact radiation thermometry is widely used in temperature measurement due to its wide range, high precision, and non-destructive nature towards the object′s original temperature field. However, in high-temperature environments where turbine blades operate, various factors interfere with radiation temperature measurements and cause errors. Among these factors, reflected radiation error accounts for the largest proportion. Therefore, suppressing such errors is vital for accurately measuring blade temperatures. The methods for correcting reflection radiation errors are summarized, such as establishing a reflection radiation model, designing reflection radiation error correction algorithms, and using dual-spectrum area pyrometry (DSAP) temperature measurement and optical path optimization methods. Based on this, the development of reflection radiation correction methods is prospected.
