A measurement system with a temperature control function was developed for mapping the vibration patterns of piezoelectric resonator devices. This system is based on the laser speckle method with intermittent device excitation. By use of a small oven with transparent windows, the vibration shapes of devices can be visualized in high temperature environment. Experimental results using a AT-cut quartz resonator show that the mode shapes can be visualized from room temperature to 74℃

开发了一种具有温度控制功能的测量系统，用于测量压电谐振器的振动模式。该系统基于激光散斑法，采用间歇式器件激励。通过使用带有透明窗户的小烤箱，可以直观地看到高温环境下设备的振动形状。利用AT切石英谐振器进行的实验结果表明，从室温到74℃，都可以观察到模式的形状
