Experimental Validation of High Spatial Resolution of Two-Color Optical Fiber Pyrometer [PDF]

Sensors, 2023
Taking non-contact temperature measurements in narrow areas or confined spaces of non-uniform surfaces requires high spatial resolution and independence of emissivity uncertainties that conventional cameras can hardly provide. Two-color optical fiber (OF)

High Spatial Resolution Optical Fiber Two Color Pyrometer With Fast Response [PDF]

IEEE Sensors Journal, 2021
Among the different temperature measurement techniques providing micrometer resolution none of them provide fast response and easy access to close distances to the target surface in difficult to access areas. Optical fiber pyrometers provide that access but previous works used large optical fibers with numerical apertures limiting the minimum spot size

In-situ measurement of cutting edge temperature and its effect on tool wear in turning by a near-infrared fiber-optic two-color pyrometer

Procedia CIRP, 2021
Abstract The cutting temperature plays an important role in the machining process. Research on the real-time monitoring of cutting temperature and its effect on tool wear still faces many challenges. In this paper, a fiber-optic two-color pyrometer is proposed to obtain temperature of cutting edge during turning at real-time.
