I hosted a webinar on December 29, 2023 on

"What happens to displacement at the antiresonance frequency of an ultrasonic transducer"

Summary

Using a laser doppler vibrometer, I demonstrate that the mechanical displacement is not affected by the antiresonance phenomenon of ultrasonic transducers.

In this webinar, I show experiments and talk about theory. I also talk about mechanical antiresonance.

My next webinar will be on Friday, January 5, 2023 at 11AM EST. I will cover

"How to measure the accuracy and linearity of an laser doppler vibrometer for ultrasonic transducers”
