Preliminary Study on Noncontact Internal Structure Sensing by Resonant Mode Excitation Using Airborne Ultrasound Radiation Pressure
نویسندگان
چکیده
In this paper, we perform the first study of noncontact internal structure sensing based on mechanical resonance mode excitation of an elastic object. The vibration is excited by airborne ultrasound acoustic radiation pressure. It is confirmed by using the noncontact sensing system that the lowest resonance frequency of the measured displacement amplitude frequency response decreases as the increasing object height.

Noncontact modal analysis of a pipe organ reed using airborne ultrasound stimulated vibrometry.
The goal of this study was to excite and measure, in a noncontact manner, the vibrational modes of the reed from a reed organ pipe. To perform ultrasound stimulated excitation, the audio-range difference frequency between a pair of ultrasound beams produced a radiation force that induced vibrations. The resulting vibrational deflection shapes were measured with a scanning laser vibrometer. The ...
متن کاملElimination of standing wave effects in ultrasound radiation force excitation in air using random carrier frequency packets.
The ultrasound radiation force has been used for noncontact excitation of devices ranging from microcantilevers to acoustic guitars. For ultrasound radiation force excitation, one challenge is formation of standing waves between the ultrasound transducer and the device under test. Standing waves result in constructive/destructive interference causing significant variations in the intensity of t...
متن کاملDesign and Production of a Pneumatic Moving Exciter for Determination of Vibration Behavior of Structures in Variable Frequencies
Determination and analysis of vibration behavior of structures for at least first few natural frequencies and mode shapes needs several sensors to be connected at different non node points and exciting the structure at one point. Other method for determination of first few mode shapes is to excite several points of the structure at once and sensing the response from one point. Both methods nee...
متن کاملAn overview of therapeutic applications of ultrasound based on synergetic effects with gold nanoparticles and laser excitation
Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...
