Emissivity Correction and Thermal Pattern Reconstruction in Eddy Current Pulsed Thermography

Sensors, 2023
Emissivity variations are one of the most critical challenges in thermography technologies; this is due to the temperature calculation strongly depending on emissivity settings for infrared signal extraction and evaluation.

A Deep Learning Method for the Impact Damage Segmentation of Curve-Shaped CFRP Specimens Inspected by Infrared Thermography

Sensors, 2021
Advanced materials such as continuous carbon fiber-reinforced thermoplastic (CFRP) laminates are commonly used in many industries, mainly because of their strength, stiffness to weight ratio, toughness, weldability, and repairability.

Defect Shape Detection and Defect Reconstruction in Active Thermography by means of Two-Dimensional Convolutional Neural Network as well as Spatiotemporal Convolutional LSTM Network

, 2022
126144A neural network (NN) for semantic segmentation (U-Net) was used for the detection of crack-type defects from thermography sequences. For this task, data sequences of forged steel parts were acquired through induction thermography and the ...

Improvement of the contrast-to-noise ratio in pulse-phase thermography by frequency dependent windowing

, 2022
Paper QIRT-2020-016, 10 S.Two modified algorithms for pulsed phase thermography were defined. The principle is to mask out parts of the thermal signal that only add noise but no significant information.

Enhanced Infrared Image Processing for Impacted Carbon/Glass Fiber-Reinforced Composite Evaluation

Sensors, 2017
In this paper, an infrared pre-processing modality is presented. Different from a signal smoothing modality which only uses a polynomial fitting as the pre-processing method, the presented modality instead takes into account the low-order derivatives to ...
