To understand heat transfers in complex system, three-dimensional temperature measurements is a powerful source of information. Various techniques exist, optical, electromagnetic, or scanning thermal microscopy, generally falling into two categories: two-dimensional measurements together with inverse methods, or direct 3D measurements requiring fewer assumptions and potentially handling more...
Among infrared thermal characterization techniques, scanning photothermal radiometry (SPR) stands out as an active technique that is simultaneously non-destructive, contactless, and allows for temporal resolutions on the order of nanoseconds and spatial resolutions down to the submicrometer scale, lower than 0.5µm [1]. It relies on measurements at different frequencies to investigate different...
Handling infrared cameras is often challenging due to the diversity of manufacturers and communication interfaces. Although camera communication may rely on generic standards such as GenICam, it frequently depends on vendor-specific Software Development Kits (SDKs) and proprietary software. As a result, integrating custom algorithms and building reproducible processing pipelines across...
The history of satellite observations of fires and flares in the infrared from space extends back to the 1970's. Most of the products relied on detection with a midwave infrared spectral band near 4 um and a longwave infrared band in the 10-12 um range. These data products are referred to as "hotspots" as it is impossible to calculate temperature or source area for subpixel heat sources from a...
This article addresses the need for dense and spatially coherent three-dimensional thermal information in short-range thermal digitization processes, where small- and medium-sized objects require an accurate representation of both their geometry and thermal distribution. Conventional two-dimensional thermography techniques, although widely used for object inspection and thermal analysis,...
Recent developments in the monitoring of marine pollution using remote sensing have focused on characterizing hydrocarbon products. However, only a few studies have examined the remote sensing of Hazardous and Noxious Substances (HNS), even though their release at sea can pose risks to human health, harm living resources, and other marine life. Unlike hydrocarbons, which generally remain on...
Physiological reactions of plants are used in bioindication as early warning indicators of environmental stress. As part of a larger project aimed at developing repeatable remote sensing methodologies for monitoring crop performance and identifying environmental stressors relevant to precision agriculture and environmental surveillance, this work presents a quantitative approach based on...
In infrared thermography, the measured surface temperature of a scene at a given time is typically presented as a thermogram. When the objective is to interpret temperature over time, analysis commonly requires visual comparison of multiple thermograms acquired sequentially. In practice, apparent temperature differences may arise not only from actual thermal changes but also from measurement...
Modern military operations routinely unfold under low visibility and strict concealment constraints. In these conditions, estimating time-since-discharge and recent firing patterns from passive sensing alone - without active illumination or other emitters - is critical to reduce misidentification and associated casualties. Passive IR observations, particularly thermal imagery, can preserve...
Infrared thermography (IRT) is a well-established non-destructive testing (NDT) technique widely used for detecting and characterizing defects in materials and structures. It offers a contactless and wide-area inspection capability, enabling the rapid evaluation of thermal responses that indicate subsurface anomalies. However, in many cases, raw thermographic data do not exhibit clear defect...
The increasing focus of the aerospace industry towards component reusability has made non-ablative material largely employed for Thermal Protection System in spacecraft atmospheric re-entry missions. In this work, special CMC TPSs obtained with ISiComp®, a Ceramic Matrix Composite (CMC) reinforced with carbon fibres, have been studied, paying special attention to the monitoring of the surface...
