Narrow spectrum blue LED lights for fire studies, monitoring

The new imaging method published in the Fire Technology journal uses digital image correlation (DIC), an optical analysis technique that compares successive images of an object as it deforms under the influence of applied forces, such as strain or heat.

By precisely measuring the movement of individual pixels from one image to the next, researchers can accumulate detailed information about how the material performs over time, including behaviors such as strain, displacement, deformation, and even the microscopic beginnings of failure.
