Witrynaidea for the principle of Lockin-Thermography. In terms of modern data analysis, the lockin principle means simply Fourier analysis at the modulation frequency where … WitrynaThe basic idea of optical lockin thermography (OLT) has been described previously [1-4]: Heat is deposited remotely by absorption of radiation. As the radiation is modulated, the generated temperature field oscillates. The local phase and amplitude are evaluated and presented as images derived from four primary images. Therefore such images ...

WitrynaThe transverse and longitudinal anisotropy ratio depends on the sintering temperature. Thus, non-constant process temperature along wall thickness results in functionally graded material properties in structural shells, which can be well characterizsed by nondestructive testing methods.
