超声波

这个装置用来确定声波的速度和在聚丙烯酸酯中超声波信号的衰减，还可以确定缺陷处的位置。它可以用来研究超声波影像和地面回路的失常现象，和分析与频率有关的分辨能力，及显示手动的B－图像。 利用超声波变频器1MHz（U10015）和4MHz（U10017）来研究分辨率。 这个磨光的聚丙烯酸酯立方体具有不同大小的钻孔，可以用来模拟位于表面的不同大小的缺陷。 规格：150×80×40 mm 更多

这个双层的容器带有橡皮薄膜和压力调整器。它可以利用时间运动技术来演示心脏瓣膜的运转。利用这个薄膜容器完成的测试可以产生与在医学诊断中心脏的超声波心动图相似的图像。 规格：160×70 mm 更多

CT scanner for turning and moving samples for the purpose of generating tomographic images. All turning and movement is carried out by means of stepper motors. While the measurement is taking place, the scanner moves the sample backwards and ... 更多

Controller for operating the two stepper motors for the linear motion axis and the rotation axis of the CT scanner. Control of motion or direction of rotation, as well as linear speed and rotational velocity can be set manually or with a PC ... 更多

Black plastic cylinder with non-uniform absorption and speed of sound within its interior. With magnetic holder for attachment to the revolving stage of the CT scanner. In the case of ultrasonic tomography, two different measurement variables ... 更多

Sample trough for CT scanner made of thin transparent plastic. Includes several special fittings for attaching and connecting ultrasonic sensors to the sides of the trough. Since transparent acrylic exhibits a very low acoustic impedance step ... 更多

Equipment set for experiments on geometric and wave-mechanical acoustics. Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used to ... 更多

The ultrasonic Doppler probe with a frequency of 2 MHz has been specially developed for measurements on the arm phantom (order no. 1022331). The pen shape and the small sound area permit simple handling and lead to sufficient local resolution ... 更多
