The Power of Laser Light: Non-Contact Strain Measurement Revealed!

Here you can see how strain can be measured without touching the specimen – using advanced laser light technology. Especially when testing small, fragile, or extremely hot materials, traditional extensometers reach their limits. The solution? Optical systems with lasers and cameras that use a method called laser speckle tracking. The strain is then measured completely contact-free and without the need to mark the specimen. Different laser colors are used depending on the temperature: Red – standard for temperatures up to 900 °C Green – performs better at high temperatures up to 1200 °C Blue – ideal for ultra-high temperatures up to 2000 °C Key advantages at a glance: ✔ No contact with the specimen ✔ No interference with test results ✔ Works at temperatures up to 2000 °C ✔ Faster and simpler setup Perfect for modern materials testing – it’s faster, safer, and more precise! 00:00 - Intro 00:30 - Laser speckle tracking 01:00 - Laser colours 01:17 - Why choose lasers?
