In the research of aero-engine test technology, Visual measurement of two dimensional temperature field is very important. In order to study the life of turbine blades and turbulent combustion problems, the most direct way is to get the temperature field. In recent years, visual temperature measurement technology based on laser diagnosis has been the mainstream of research. laser induced phosphorescence (LIP), planar laser induced fluorescence (PLIF), and tunable diode laser absorption tomography (TDLAT) has been gradually applied in the field of aero-engine. This paper mainly introduces the above three methods of aero-engine temperature field measurement based on laser diagnosis, the basic principle and research status at home and abroad are reviewed, the advantages and disadvantages of different temperature measurement techniques are analyzed, as well as the scope of application. Finally, the main existing problems and development trends are discussed.
