温度是大多数技术燃烧系统（例如燃气轮机、熔炉或内燃机）中主要关注的标量之一。在这项工作中，我们首次提出了通过基于时域的超连续谱吸收光谱对火焰进行定量温度测量。在一维 McKenna 型燃烧器中，通过多峰最小二乘算法从宽带 H2O 光谱中推断出 1340 nm 至 1485 nm 光谱范围内 Barber-Tennyson 线表 (BT2) 的数据。将结果与基于相干反斯托克斯拉曼散射 (CARS) 的温度测量进行比较。取得了良好的一致性，显示了基于时域的超连续谱吸收光谱测量火焰温度的能力。此外，还介绍了高带宽检测设备的有益影响，其允许对多周高温转变进行更清晰的检测。
Temperature is one of the scalar quantities of major interest in most technical combustion systems such as gas turbines, furnaces or internal combustion engines. In this work, we present for the first time quantitative temperature measurements in a flame by time-domain based supercontinuum absorption spectroscopy. In a 1-dimensional McKenna type burner temperature is inferred from broadband H2O spectra by a multi-peak least-square algorithm to data from the Barber-Tennyson line list (BT2) within a spectral range from 1340 nm to 1485 nm. The results are compared with temperature measurements based on coherent anti-stokes Raman scattering (CARS). A good agreement is achieved, showing the capability of time-domain based supercontinuum absorption spectroscopy temperature measurements in a flame. Further the beneficial influence of high bandwidth detection equipment is presented, which allows for a more distinct detection of many week high temperature transitions.
