By launching a mid-infrared laser signal in a fiber core and recording its side scattering with a wide spectrum infrared camera, scientists are able to screen optical fibers for defects – an crucial step in the development of high-power infrared lasers.

The presence of cracks and defects changes the thermal properties of the materials. Infrared imaging provides unique insights for remote inspection of various objects such as electronic components and artworks where non-contact analysis is more suitable. The correct interpretation of thermal flows can reveal the presence of structural changes within the material and prevent failures.
