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, 基底状態を経て、特定の振動エネルギーレベルを持つ励起状態に遷移します。. ただし、励起状態は安定ではなく、平衡に戻る可能性があります。, 外部励振源が動作を停止したとき, 発光現象は一定時間継続します, それを残光と呼ぶ. 加えて, 蛍光分子の不活性化プロセス中, 不安定な励起状態の分子は、エネルギー準位遷移を通じて高エネルギー準位から低エネルギー準位に遷移します。, 過剰なエネルギーは電磁放射の形で光を放出します。. したがって, さまざまな励起方法に従って, フォトルミネッセンスに分けることができます, エレクトロルミネッセンス, 化学発光, そして生物発光.

プランクの法則によると, 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

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

E2- Energy of electrons at higher energy levels;

K – プランク定数;

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. したがって, 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, 蛍光温度測定が可能. したがって, 一般に蛍光強度温度測定法に分けられます。, 蛍光寿命温度測定方法, およびレーザー誘起蛍光法. その中で, 蛍光寿命温度測定法は励起光源の強度の影響を受けにくい, 結合度, 温度測定プロセスにおけるファイバー伝送効率と, 使用するとさらに明らかな利点があります. 温度測定原理は、励起光源を取り除いた後、, 蛍光物質が蛍光を発し続ける時間を蛍光寿命といいます。, それは励起状態の寿命に依存します. 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)

In the formula: Rs, RT, K, Δ E – constant;

T – thermodynamic temperature.

これから, 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.
