It has been reported by FLIR Systems how its FLIR A6700 series thermal cameras with Lock-In, Transient, and Pulse capabilities can perform advanced inspections such as Non-Destructive Testing (NDT) or stress mapping, resolving temperature differences as low as 1mK.
NDT is widely used to evaluate the properties of a material, component, or system without causing damage. FLIR A6700sc series cameras can detect internal defects through target excitation and the observation of thermal differences on a target's surface. Thermal imaging is a valuable tool for detecting defects and points of failure in composites, solar cells, bridges, and electronics. It is also a great tool for thermal mapping of stress when performing materials testing.
Thermal non-destructive testing using a FLIR A6750 SLS longwave infrared thermal camera can detect internal defects through target excitation and the observation of thermal differences on a target surface. This camera is also proven to be a valuable tool for detecting voids, delamination, and water inclusion in composites.
