Ultrasonic/Megasonic Cleaning Tank Scanner (CTS) - Video
Onda is developing a hydrophone scanning system (CTS) to characterize the acoustic field in ultrasonic and megasonic cleaning systems. The CTS scanner enables hydrophone measurements to be done automatically, using the HCT hydrophone (https://www.ondacorp.com/cleaning-tank-hydrophones/). The CTS is designed to mount to substrate carriers, eliminating the need for positioning alignment. Because ...

Ultrasound Waves Small Aluminum Tube - Video
Schlieren video of an ultrasonic pulse generated by a 5 MHz curved array. The acoustic beam has a small aperture and it is aimed at the center of a 10 mm diameter plastic tube. The reflected wave off the surface is seen as well as subsequent internal reflections and transmissions by the ...

Ultrasound Image of Waves Hitting Large Aluminum Tube - Video
Schlieren video of a wave pulse generated by a 5 MHz curved array, as it bounces from the external and internal surface of a thin-walled aluminum can (soft drink). Note how the curvature of the can forces the pulse to re-focus after each internal ...

Ultrasound Image of Waves in Reverb - Video
Schlieren image of an ultrasonic pulse generated by a 5MHz curved array. The pulse propagates away from the transducer and then hits a partially reflecting surface, showing several bounces. Note the sidelobes as well as the trailing whiskers of the pulse, both consequences of the finite aperture ...

transparent Block Ultrasound Imaging - Video
Superposition of two images: a schlieren image of a HIFU (High Intensity Focused Ultrasound) transducer, which is shown as a blue background and mostly blue beam, at the beginning, and a video of color-indicating gel as a rectangle, both registered at exactly the same location. The transducer generates a high intensity field which heats up the gel which in turn changes from transparent to white ...

Ultrasound test of tube 2 Video
Schlieren video of an ultrasonic pulse generated by a 5 MHz curved array. The acoustic pulse strikes an 18 mm diameter plastic tube. The reflected wave off the surface is seen together with a wave caused by a surface wave on the tube, as well as a subsequent pulse caused by an internal reflection and transmission through the ...

Absorptive Sound Wall Systems - Video
Sound barrier walls fall into one of two categories: reflective and absorptive. Let’s compare reflective and absorptive to get a better understanding. Barriers without any additive absorptive treatment or design such as block, concrete, wood, or metal are considered reflective. This means in the case of highway applications for example the sound energy actually bounces from one side of the ...
