Key Points

The vibrometer captures surface vibrations at 1 gigahertz, showcasing high-speed imaging capabilities.
With a noise floor of 120 fm/sqrt(Hz), this technology significantly enhances vibration measurement accuracy.
Imaging a 110 x 210 micron device can be achieved in just 10 minutes, highlighting efficiency.
Employing spectral interferometry allows for detailed analysis of surface acoustic waves in real-time.

Implication

This research demonstrates measuring gigahertz frequency vibrations using a linescan camera, indicating new imaging techniques.

Abstract

We measure 1 gigahertz surface vibrations with spectral interferometry on a 76 kilohertz linescan camera. The vibrometer has a noise floor of 120 fm/sqrt(Hz) and images a 110 x 210 micron device in 10 minutes.
