用三步相移法测量温度场

MEASURING TEMPERATURE FIELD WITH THREE-STEP PHASE-SHIFTING

  • 摘要: 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。

     

    Abstract: A two-reference phase-shifting method is used to meaisure temperature fieldin this paper.Because the phaise-shifting is introduced during reconstructing,it overcomesdisadvantges which exist in introducing phase-shifting during recording.Using this method,we can measure not only quasi-state field , but also transient field.we also adopt a newmethod to calculate the temperature field distribution in this paper.Experimental resultsillustrate that the method inproves measurement speed and precision.
