提出了一种采用双参考光光路，并在再现阶段引入相移的方法来测量火焰温度场，克服了在记录阶段引入相移的不足，采用这种方法不仅可以测量准静态场，而且可以测量瞬态场。本文在计算温度时还采用了新的求解方法，守验表明这种方法提高了测量的速度和精度。
A dual reference light path is introduced and the phase shift is introduced to measure the temperature field of the flame. This overcomes the shortcoming of introducing phase shift in the recording stage. This method can not only measure the quasi-static field but also measure Transient field. In this paper, a new method is also used to calculate the temperature. The test shows that this method improves the speed and accuracy of the measurement.
