“…The amount of infrared radiation emitted is different for each part of the animal [52]. According to the studies conducted, the recommended range of emissivity values is 0.95-0.97 for furred skin in mammals, e.g., see [53][54][55], but according to [56], sufficient determination of fur emissivity is essential to obtain accurate temperature data, which is influenced by various factors and thus the emissivity range used cannot be applied to all individuals or species.…”

Infrared thermography (IRT) is a noninvasive and safe method of displaying the temperature map of objects that can be used to detect hoof diseases and lameness to reduce significant financial costs and physically stress animals. A qualitative bibliometric method based on the analysis of publications by the authors themselves using sophisticated tools of scientific databases was applied in this work. This review presents the fundamentals of IRT as well as recent developments in IRT detection in dairy science, including preprocessing, segmentation, and classification of objects in IRT images. In addition, recent studies dealing with the detection of hoof diseases and lameness using IRT are reviewed. As a result of this study, select previous studies are confronted in terms of technical aspects of IRT measurements such as emissivity, distance, temperature range, and reflected air temperature. Subsequently, recommendations for future IRT measurements are discussed.

“…The detection process of this technology is non-polluting and non-destructive. It works by detecting the infrared radiation emitted from the object surface and converting it to temperature [1] . As an emerging non-destructive testing (NDT) method which integrates eddy current testing and IRT, eddy current pulsed thermography (ECPT) has been applied for defect detection in metallic materials [2] .…”

Eddy current pulsed thermography (ECPT) is an effective non-destructive testing (NDT) technique for detecting flaws in metallic materials. However, due to the low radiation and high reflection properties of metallic materials, as well as the inhomogeneous emission caused by the complex states of the material surface, the detection of subsurface defects becomes difficult. In this paper, the physical mechanisms underlying the interference of the thin water film in ECPT detection are studied. Two static comparative experiments have been carried out on the ferromagnetic plate with several artificial subsurface defects. In the first comparative experiment, a high radiation point has been artificially added near the defects. The experimental results showed that water film could eliminate the influence of inhomogeneous emission. In the second experiments, the effectiveness of water film in improving the detectability of subsurface defects has been demonstrated and the subsurface defects with a maximum buried depth of 0.4 mm can be detected.
