A possibility of calibrating a piezo transducer by comparing thermoacoustic and vaporization pressure signals generated in a metal (liquid mercury) irradiated with nanosecond laser pulses is demonstrated. In this calibration method, significant difference in the dependence of these two pressure generation mechanisms on the irradiated surface temperature is used.

通过比较金属靶的脉冲激光辐照下的热声和汽化压力信号对压电传感器进行纳秒校准

演示了通过比较用纳秒激光脉冲照射的金属（液态汞）中产生的热声和汽化压力信号来校准压电换能器的可能性。在该校准方法中，使用了这两种压力产生机理对照射表面温度的依赖性的显着差异。
