The temperature measurement principle of fiber optic temperature sensors

The fluorescence temperature measurement device manufactured based on the functional relationship between fluorescence afterglow lifetime and temperature has advantages that traditional temperature measurement methods cannot compare with.

The basic principle of fluorescence temperature measurement

When a substance is excited, such as by short wavelength visible or ultraviolet light, electric field excitation, or chemical reactions, it will absorb and store energy, and transition to an excited state with a certain vibrational energy level through the ground state. But the excited state is not stable and may return to equilibrium, and when the external excitation source stops working, the luminescence phenomenon will continue for a period of time, which is called afterglow. Además, during the deactivation process of fluorescent molecules, unstable excited state molecules will transition from high energy levels to low energy levels through energy level transitions, and the excess energy will emit light in the form of electromagnetic radiation. Por lo tanto, according to the different excitation methods, it can be divided into photoluminescence, electroluminescence, chemiluminescence, and bioluminescence.

Según la ley de Planck, when the energy of the incident light is received by the luminescent material, it will excite electrons in the material to produce electron level transitions, and this process will produce outgoing light with a wavelength of λ. The formula for the energy difference between high and low energy levels is:

E2-E1=k λ v=kf

en la formula: E1- the energy of the electron at a lower energy level;

E2- Energy of electrons at higher energy levels;

k – Planck constant;

V – the propagation speed of light in vacuum;

F – frequency of light;

λ – The wavelength of the emitted light.

Due to E1 and E2 being in different energy bands, they represent light in a certain band, while the energy in the molecule includes rotational energy generated by electrons and vibrational energy caused by axial elastic vibrations between nuclei. Por lo tanto, when molecules absorb light radiation, after quantum transitions, the electron energy will rise from the ground state to a higher energy level, and the rotational energy and vibrational energy will change simultaneously, causing the three energies to interact with each other. After the incident light disappears, the luminescent material will continue to emit light for a period of time, and the emitted light is fluorescence; High frequency and short wave light energy will excite long wave and low frequency light, and follow Stokes’ law.

The basic theoretical basis of fluorescence measurement method is that when the intensity of the fluorescence linear spectrum shows monotonicity with temperature, and the temperature of the fluorescent substance determines the time of the light quenching process, fluorescence temperature measurement can be carried out. Por lo tanto, it is generally divided into fluorescence intensity temperature measurement method, fluorescence lifetime temperature measurement method, and laser induced fluorescence method. entre ellos, the fluorescence lifetime temperature measurement method is not easily affected by the intensity of the excitation light source, coupling degree, and fiber transmission efficiency in the temperature measurement process, and has more obvious advantages in use. The temperature measurement principle is that after the excitation light source is removed, the time for the fluorescent substance to continuously emit fluorescence is called the fluorescence lifetime, which depends on the lifetime of the excited state. The fluorescence lifetime of fluorescent substances is related to the corresponding temperature within a certain temperature range. Fluorescence lifetime refers to the time it takes for the fluorescence intensity to decay to 1/e of its original intensity when the excitation light source is cut off, and its relationship with temperature can be expressed as:

t (t)=1+e – Δ E/(KT) Rs+RTe – Δ E/(KT)

en la formula: Rs, RT, k, Δ E – constant;

t – thermodynamic temperature.

From this, it can be seen that the time constant of fluorescence afterglow decay is a single valued function of temperature and is only related to temperature.
