MEASURING TEMPERATURE FIELD WITH THREE-STEP PHASE-SHIFTING

  • 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.
