MODULAR DEVICE FOR STRUCTURAL DIAGNOSTICS OF VARIOUS MATERIALS AND STRUCTURE, USING THERMOGRAPHIC TECHNIQUES BASED ON MULTIPLE EXCITATIONS

摘要

The modular device includes a thermal group of excitation, a thermocamera, a capture card, at least one computer and related software for the management and control of the apparatus, at least one feedback controller of the emission levels of the waves used by the thermal group of excitation, one or more laser pointing systems for the identification of the measurement area. The thermal group of excitation is operated by a driver board, analog or digital, through ON / OFF commands and/or square and sine waves. The device is applied, in general, in the field of non-destructive testing (NDT) and, in particular, for the analysis and for the diagnostic of coatings and other details of components and big structures with specific regard to the fields of aviation industry, recreation industry, manufacturing and renewable energy.
