Introduction
Several methods have demonstrated the use of terahertz waves to estimate the mass diffusion coefficient under transient conditions. Monitoring transient water content is recognized as a key parameter in many drying processes (e.g., wood, paper, etc.). Some techniques allow water content to be measured locally – for example, in geology, where time-domain reflectometry (TDR)...
The increasing complexity of industrial systems in the aeronautical sector, together with strict safety, reliability, and energy efficiency requirements, is driving the development of new advanced monitoring and predictive maintenance strategies. In this context, infrared thermography has established itself as a key technology for non-destructive inspection, enabling continuous, real-time,...
INTRODUCTION Zero-Defect Manufacturing (ZDM) is an emerging European industry paradigm focused on reducing waste and costs while maximizing product quality. Non-Destructive Inspection (NDI) systems integrated into production lines enable proactive quality assessment. This work presents openZDM project results, focusing on InfraRed Thermography (IRT) across three industrial use cases. The...
As semiconductor packaging advances toward high density integration and heterogeneous integration, internal packaging defects such as voids, cracks, and interconnect failures become increasingly concealed. Conventional active infrared thermography (AIT) is constrained by thermal diffusion in packaging materials, which makes accurate localization and depth resolved interpretation of internal...
Production test hardware for manufacturing semiconductor devices enables the assurance of quality and performance as part of the semiconductor manufacturing process, strongly required for providing defect-free and reliable high-performance products in challenging and safety-relevant application areas such as automotive, data centers, consumer devices and industrial machinery and automation....

Detailed inspections of aircraft bodies are designed to detect and characterize damages, whether accidental (impact) or progressive (mechanical fatigue, ageing), and affecting the integrity of the aircraft structure. These inspections, mainly non-destructive tests (NDT), are carried out as part of planned maintenance operations or following the detection of damage. They are time-consuming,...
Laser sintering of metal micro- and nanoparticles commercial pastes is a promising route for fabrication of high-resolution conductive patterns on temperature-sensitive substrates. However, the narrow processing window between insufficient sintering and substrate damage remains a major challenge, particularly for copper-based materials prone to oxidation and pore formation.
In this work, high...
Resistance spot welding is the process used in the automotive industry to assemble body-in-white. A high current allows the melting temperature of steel sheets to be reached by Joule heating in a few milliseconds.
An experimental setup was developed to measure the contact temperature during welding. A high-speed infrared camera equipped with a G1 microscopic lens is used. The measurement is...
Recent EU climate policies and international reporting standards, including OGMP 2.0, have imposed stringent requirements on methane emissions from the oil and gas sector. Due to its high global warming potential, methane has become a major regulatory target, with industrial flares used for waste gas disposal required to achieve at least 99% methane destruction efficiency. These requirements...
Infrared thermography is a reliable, non-destructive method for assessing the condition of ballasted railway track superstructures, with proven applicability in evaluating ballast and concrete sleeper condition as well as switch heater functionality. Fine particles generated by the fragmentation of ballast material under traffic loading accumulate within the ballast bed, reducing its strength...
The aerospace industry frequently employs hard coatings, such as chrome plating, on sealing areas of critical components to enhance surface durability and maintain functional tolerances. Achieving optimal coating thickness and surface finish typically requires meticulous grinding. However, this process can sometimes introduce grinding burns on the substrate material, which may or may not...
