Measurement of Airborne Ultrasound Using Laser Doppler Vibrometry
The speed of light in air is dependent on the air’s instantaneous density. Since air density is modulated by sound, sound in the air can be observed and measured using optical methods. One such optical method ...

Magnetoelastic Vibration Sensors
In this work, we explore the application of magnetoelasticity towards the realization of vibration transducers. Such sensors have unique and complementary properties when compared against more conventional tra...
