IEEE Trans Ultrason Ferroelectr Freq Control. 2010 Jan;57(1):189-92. doi: 10.1109/TUFFC.2010.1397.
Ultrasonic probes which can simultaneously generate and receive 2 orthogonal polarized shear (S(perpendicular) and S(//)) and longitudinal (L) waves in screw shape have been presented. Thick piezoelectric films are directly fabricated onto the heads of such probes as L wave integrated ultrasonic transducers. S(perpendicular) and S(//) waves are obtained using mode conversion method. Potential applications of such probes are discussed.
已经提出了一种能够同时产生和接收 2 个正交偏振剪切波(S(垂直)和 S(//))和纵向(L)波的超声探头。将厚压电薄膜直接制作在这种探头的头部作为 L 波集成超声换能器。使用模式转换方法获得 S(垂直)和 S(//)波。讨论了这种探头的潜在应用。
