The basic temperature measurement principle of point type fiber optic temperature sensors in practical applications is that the critical edge of the semiconductor absorption spectrum will change with temperature and move accordingly. It can establish effective analysis and judgment of the degree of change after the semiconductor chip undergoes light intensity processing. 加えて, the absorption rate of semiconductor media is directly related to the bandgap width of the semiconductor during the process of light absorption. After the temperature changes, thermal expansion and temperature changes will affect the vibration state of the crystal, causing changes in the actual width parameter of the bandgap and resulting in abnormal absorption spectra.

Under certain conditions, the thickness of the light source illumination varies. The projected light intensity needs to be measured for specific parameters with the help of It ddt RR I α α − − −=1 e (1) e22. その中で, R represents the power reflection coefficient of the entire light source illumination system, which is proportional to the refractive index, extinction coefficient, and incident angle of the material; D represents the actual thickness of the entire semiconductor structure; α represents the absorption coefficient of the semiconductor material itself. By combining actual measurement data, it is possible to effectively analyze the actual level of the corresponding system, and by combining the relationship between the light source wavelength determination function, calculate the integral over the entire wavelength range. つまり, in practical operation, selecting an incident broadband light source and matching photodiodes can effectively calculate and analyze the transmitted light intensity, and the relevant parameters can also show different trends with changes in environmental temperature, effectively improving the overall efficiency of temperature detection work.
