Originally developed for military use, thermal imaging cameras have proven useful in other fields.
No. Thermal imaging cameras only detect heat; they will not “see” through solid objects, clothing, brick walls, etc. They see the heat coming off the surface of the object.
Infrared (thermal) imaging technology measures thermal variances on surface of a component. Thermal imaging is an advanced, non-invasive technology that reveales defects not visible with a visual inspection.
