用相移方法测量温度场

Temperature Field Measurement Using Phase-Shifting Method

本文提出了一种采用双参考光光路，并在再现阶段引人相移的方法来测量火焰温度场，它克服了在记录阶段引人相移的不足。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。实验表明这种方法提高了测量的速度和精度．

A two-refrence phase-shifting method is used to measure temperature field in this paper.Because the phase is introduced in reconstructing stage,it overcomes disadvantges which exist in introducing phase-shifting in recording stage. Using this method,we can measure not only quasi-state field,but also transient field.We also adopted a new method to caculate the temperature field distribution in thispaper.Experimental results illustrate that the method improves measurement speedand precision.
