Multiplexed lock-in thermography

Review of Scientific Instruments, 2021
Many modern measurement methods for heat transfer work in the frequency domain. A certain average temperature rise in the sample is unavoidable if the sample can only be heated, e.g., by an intensity modulated light source. This average temperature rise influences the measured thermal properties because they are, in general, temperature dependent. Here,

Glued structures inspection based on lock-in thermography

SPIE Proceedings, 2015
Active thermography is a widely employed technique for parametric identification and non-destructive inspection. This attractive method is based on the observation of thermal waves propagation induced by a periodic heating. For nondestructive testing usual approaches are based on a global heating (a large surface of the inspected material is submitted ...

THE USE OF LOCK-IN THERMOGRAPHY IN INDUSTRIAL APPLICATIONS

Nondestructive Testing and Evaluation, 2000
Abstract A feasibility study is made to search if lock-in thermography can be usefully employed in non-destructive evaluations of different materials of industrial interest. Several specimens, made of different materials and with defects artificially created to simulate either delaminations, or cracks, or inclusions of spurious materials, are ...
