Abstract
- This paper reports a new optical fiber thermometer (OFT) for ultra-high temperature measurement under extreme environments, such as in molten steels. This sapphire fiber-based OFT was designed by coating the sapphire fiber core with a nanorod cladding material, which is then housed inside the ceramic tube, the cladded sapphire fiber can collect thermal emissions from ceramic tube and couple the emission to a near-infrared spectrometer with minimal loss. After dipping OFT into molten steel, real-time temperature can be determined by analyzing the emission spectra using a polynomial curve fitting or a machine learning-based classification algorithm.
