Nondestructive Detection of Osmotic Damage in GFRP Boat Hulls Using Active Infrared Thermography Methods

Journal of Marine Science and Engineering
This article presents the application of infrared thermography as a nondestructive testing method (NDT) for detecting osmotic damage in glass-fiber-reinforced polymer (GFRP) and glass-reinforced polymer (GRP) boat hull structures.

Noninvasive Methods of Active Thermographic Investigation: Short Overview of Theoretical Foundations with an Example of Application

Energies, 2022
The field of non-destructive testing using thermography (NDT—Non-Destructive Testing and NDE—Non Destructive Evaluation) was established in the 1960s as a competitive and complementary method to ultrasonic or X-ray testing.

Infrared Thermography in Sports Activity

, 2012
The origin of infrared thermography comes in 1800 when William Herschel discovered thermal radiation, the invisible light later called infrared, but only in the mid-sixties infrared thermography became a technique of temperature cartography. He proved that this radiation, called infrared, followed the same law as visible light.

A level‐set method for inhomogeneous image segmentation with application to breast thermography images

IET Image Processing, 2021
Various level‐set methods have been suggested for segmenting images with intensity inhomogeneity as local region‐based models. The challenge in these methods is segmenting the inhomogeneous images with smooth edges.

Active Thermography with frequency modulated source

Proceedings of the 2018 International Conference on Quantitative InfraRed Thermography, 2018
Active Infrared Thermography is applied on a CFRP slab, prepared with teflon inserts of various dimensions and located at different depths, to simulate the presence of defects inside the material. The aim is that of comparing the pulse, the periodically modulated, the chirp methods of heating.

Infrared Thermography for Temperature Measurement and Non-Destructive Testing

Sensors, 2014
The intensity of the infrared radiation emitted by objects is mainly a function of their temperature. In infrared thermography, this feature is used for multiple purposes: as a health indicator in medical applications, as a sign of malfunction in ...
