Estimating TOF from ultrasound signal over bare steel sample of 5 mm thickness

These data have been obtained using the CEIT ultrasound testbed exciting a PZT piezoelectric sensor with a +/-15 volts pulse located over a 5 mm bare steel sample. The testbed receives the ultrasound response and estimates the TOF measuring the distance between two consecutive echoes. The aim is to develop an embedded system to measure the loss of thickness produced by corrosion.本数据集通过CEIT超声测试平台采集所得：该平台采用幅值为±15伏特的脉冲信号激励PZT压电传感器（PZT piezoelectric sensor），并将传感器部署于厚度为5毫米的裸钢试样上方。该测试平台接收超声回波信号，并通过计算两次连续回波之间的时间差来估算飞行时间（Time of Flight，TOF）。本数据集的研发目标为开发一款嵌入式系统，用于测量腐蚀导致的钢材厚度损失。
