在本文中，我们描述了使用声反射器的温度测量。反射器将声音路径的数量增加到五个。利用一个扬声器（SP）和一个麦克风（MIC）利用SP的径向传输和声音的镜面反射来测量温度分布。声音的传播路径可以用作声音探针，并且可以使用具有平面表面的声反射器来改变声音的方向。通过在传播路径到达MIC之一时调整声反射器的角度，可以测量测量对象中的任意部分空间的温度分布。用一个SP、一个MIC和10个声反射器测量了被划分为5个单元格的水平空间的温度分布。SP的-6dB波束宽度约为80度，因此接收到的信号保持足够的幅度。实验结果表明，与热电偶测量的温度分布结果吻合良好。
In this paper, we describe temperature measurement using acoustic reflectors. The reflectors increased the number of sound paths to five. The temperature distribution was measured with one loud speaker (SP) and one microphone (MIC) utilizing a radial transmission of the SP and specular reflections of sounds. The propagation paths of the sounds could be used as the sound probes and their directions could be changed using the acoustic reflectors with plane surfaces. By adjusting the angles of the acoustic reflectors as the propagation paths reached one of the MICs, the temperature distribution of an arbitrary and partial space in the measurement object could be measured. The temperature distribution of a horizontal space partitioned into five unit cells was measured with one SP, one MIC and ten acoustic reflectors. The -6 dB beam width of the SP was approximately 80 deg, thus the received signals maintained sufficient amplitudes. Experimental results showed a good agreement with the temperature distribution results measured with thermocouples.
