研制成功一种便携式实时B型扫描超声装置,其接触式探头由128个微型压电体阵列组成。该装置采用电子方法控制超声束的扫描、聚焦和偏转。它具有多种功能,可显示缺陷的取向、位置与长度等特征,还可测定在役期内这些缺陷的变化。 Developed a portable real-time B-scan ultrasound device, the contact probe consists of 128 miniature piezoelectric array. The device electronically controls the scanning, focusing and deflecting of the ultrasound beam. It has a variety of features to show the orientation, location and length of defects and other features, but also to measure changes in service during these defects.
