摘要
Problem: the pressure in the engine core is directly measured, the pressure pipe is eliminated, the weight is reduced, and the measurement accuracy is improved.Two narrow band light sources having different peak frequencies are combined using coupler to combine light.The combined light is divided into a first Fabry Perot interferometer positioned so as to be directed to both the temperature and the target physical parameters and a second Fabry Perot interferometer positioned to be irradiated only at the temperature.The system further comprises first and second photodetectors disposed to receive light reflected from the cavity of the first and second Fabry Perot interferometers, respectively, through an optical path consisting of a lens or mirror and a fizo interferometer.The processor is designed to analyze the data received by the first photodetector and the second photodetector and calculate the values of the temperature and the physical parameters of the object.Diagram
