Surface roughness influence on photothermal radiometry

نویسنده

  • H. G. Walther
چکیده

Surface roughness has to be taken into account for accurate interpretation of photothermal measurements. An expression for photothermal signals from rough samples was derived by combining the effect of roughness induced thermal wave dispersion with the equivalent layer model. The performance of the proposed model was successfully demonstrated by comparing calculations with radiometric measurements from rough steel samples.

Photothermal Radiometry – Principle and Applications

Photothermal radiometry has been proved being a versatile tool for the non-contact and non-destructive material inspection in near-surface zones. Although these near-surface areas represent only a few percent of the workpiece’s volume, they influence significantly its quality, functional behaviour, reliability and life time. In particular, they determine decisively the mechanical properties of ...

Influence of microwave treatment on surface roughness, hydrophobicity, and chemical composition of galena

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

Experimental Modelling of Ir Nonlinear Photothermal Radiometry in Carbon/epoxy Composite Materials

The potential of thermal nonlinear effects in composite materials was investigated for nondestructive testing. Second harmonic generation in thermal-wave fields has attracted much attention in recent years for the non-destructive evaluation of solid structures. Even though not the only source, the presence of a defect can result in a strong nonlinear signature, which could enhance the detectabi...

Digital Surface Models for the estimation of hydraulic properties of soils

Various applications such as meteorology, climatology or hydrology require information about the soil hydraulic properties over large areas. Microwave radiometry is a promising approach to gather this type of information. The microwave emission from soils is strongly affected by the roughness of the soil surface. This effect has therefore to be quantified to get a reasonable estimation of the h...
