Описание к видео Why use lasers in vibrometers?

Why do we use a laser as a light source in vibrometers? Why not grab a light bulb from Home Depot and use that instead? That’s because a laser has some unique properties that make it a perfect fit for vibrometry. Let’s look at these properties in this video. Polytec and the field of vibrometry in general owes its existence to lasers. Here’s a fun fact. The first laser was built in 1960. Polytec was formed in 1967 – which shows the vision of the founders and the long-term commitment that we take pride in.
