Example Sentences

They played sound ranging from 1 Hz to 50 kHz for the spiders and measured the spider silk motion with a laser vibrometer.

From Science Daily

In a new study, published online today in the Proceedings of the National Academy of Sciences, researchers used a laser vibrometer—a tiny machine that hits the bee hair with a laser—to measure how the hair on a bee’s body responds to a flower’s tiny electric field.

From Science Magazine

As the hair moves because of the electric field, it changes the frequency of the laser light that hits it, allowing the vibrometer to keep track of the velocity of motion of the hair.

From Science Magazine

“But if you use a device called a laser vibrometer, which detects very small vibrations, you hear this crazy rumbling sound. They actually sound like lions!”

From National Geographic

They placed the feathers in a wind tunnel and used a Doppler vibrometer to measure the vibrations.
