TB Series Piezoelectric Tube Scanners TB系列压电管扫描仪

Piezoelectric tube scanners are thin cylinders of radially poled piezoelectric material with four external electrodes and a solid or quadrant internal electrode. When a voltage is applied to one of the external electrodes, the actuator wall expands which causes a vertical contraction and a large lateral deflection of the tube tip. A circumferential electrode can be used for vertical or radial extension and contraction.

压电管扫描仪是具有四个外部电极和实心或象限内部电极的径向极化压电材料的薄圆柱体。当电压施加到一个外部电极时，致动器壁膨胀，导致管尖的垂直收缩和大的横向偏转。圆周电极可用于垂直或径向伸展和收缩。

Piezoelectric tube scanners are used extensively in scanning probe microscopes and applications such as fiber stretching and beam scanning.

压电扫描仪广泛用于扫描探针显微镜和光纤拉伸和光束扫描等应用。
