Journal ArticleDOI
Multi-Wavelength Pyrometry
TL;DR: The main problem in the application of radiation pyrometry to the measurement of true surface temperatures is the large error arising from the unknown or varying emissivity of the surface.
Journal ArticleDOI
Optical monitoring of Nd : YAG laser cladding
TL;DR: In this paper, a bi-dimensional monochromatic (0.860 μm wavelength, 2.5×2.5 mm2 vision zone, 1.7 ms acquisition time) and 1-spot multi-wavelength pyrometers are applied for surface temperature monitoring in Nd:YAG laser cladding.
Journal ArticleDOI
Comparison between multiwavelength infrared and visible pyrometry: Application to metals
TL;DR: In this article, a multi-wavelength pyrometry was used to address the issue of nonintrusive temperature measurements of metallic materials, where the emissive properties of the metal cannot be known a priori.
Journal ArticleDOI
Multi-wavelength radiation pyrometry where reflectance is measured to estimate emissivity
J L Gardner,T P Jones +1 more
TL;DR: In this article, a multicolour radiation pyrometry technique is described, where the directional emissivity of the surface whose temperature is being sought is estimated from measurement of a surface reflectance factor.
Journal ArticleDOI
Multiwavelength infrared pyrometry: optimization and computer simulations
TL;DR: In this paper, the authors present a preliminary study concerning a multi-wavelength pyrometry method, which may be useful for temperature measurements on materials of unknown, selective, rapidly varying emissivity.
