Influences from environment are inducing structural damage, modification of materials and agglomeration of pollutants, salt and microorganisms which first become visible at outer or inner surfaces of historic buildings. Non-destructive testing methods and especially active thermography are well suited for assessing and monitoring the condition and modification of facades. Active thermography me...

Transient thermography, which employs pulse surface heating of an inspected component followed by acquisition of the thermal decay stage, is gaining wider acceptance as a result of its remoteness and rapidness. Flaws in the component’s material may induce a thermal contrast in surface thermograms. An important issue in transient thermography is estimating the depth of a subsurface flaw from the...

Self-heating induced failure of graphene devices synthesized from both chemical vapor deposition (CVD) and epitaxial means is compared using a combination of infrared thermography and Raman imaging. Despite a larger thermal resistance, CVD devices dissipate >3x the amount of power before failure than their epitaxial counterparts. The discrepancy arises due to morphological irregularities implic...

Different parameters influence the results of infrared measurements of temperature. The emissivity of the surface under consideration as well as the temperature of the ambient elements may be specified among these parameters. Convective and radiative heat transfer takes place between thermal pipelines and its surrounding. In the case of low temperature of the sky, the radiation heat exchange is...

The process of adsorption of water-vapour molecules on uneven (irregular) surfaces of some solid materials at room temperature is registered by infrared camera. The pronounced "thermal flame" ("thermal fire") phenomenon developing on the samples’ surfaces is exhibited and quantitatively represented. This thermal effect ranged within an order of magnitude. 3-μm-wavelength emissivities of differe...

The rapid development of genomic technology has made high throughput genotyping widely accessible but the associated high throughput phenotyping is now the major limiting factor in genetic analysis of traits. This paper evaluates the use of thermal imaging for the high throughput field phenotyping of Solanum tuberosum for differences in stomatal behaviour. A large multi-replicated trial of a po...

The vision technology and in particular the thermography testing (TT) is a rapid developing NDE method within the nuclear industry. This paper proposes a new approach based on TT and anomaly detection algorithms for the detection of defects in nuclear components. The novelty of the approach consists of using a processing method, originally developed for multiand hyperspectral imagery, for the a...
