... ). This paper presents a multicolor pyrometry system respectively based on a fiber optic spectrometer and a color charge coupled device (CCD), which does not require geometry calibrations, as an extension of the two-color pyrometer. The radiation intensity ratio (the relative intensity) of different wavelengths...

...N. Ranc; V. Pina; G. Sutter; S. Philippon The working processes of metallic materials at high strain rate like forging, stamping and machining often induce high temperatures that are difficult to quantify precisely. In this work we, developed a high-speed broad band visible pyrometer using...

...K. Dai; X. Li; L. Shaw Thermal analysis of laser densification of a dental porcelain powder bed has been investigated using a three-dimensional thermal finite element model, which encompasses (i) the incoming laser beam power with a Gaussian distribution, (ii) optical pyrometer simulation...

...Frank E. Pfefferkorn; Frank P. Incropera; Yung C. Shin A procedure using a long-wavelength pyrometer is developed for the measurement of surface temperatures on materials that are semitransparent at shorter wavelengths, and specific application is made to a dense zirconia ceramic (Mg-PSZ...
