Experimental Validation of High Spatial Resolution of Two-Color Optical Fiber Pyrometer. [PDF]
Sensors (Basel), 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)

Two-Color Pyrometer for Process Temperature Measurement During Machining [PDF]
Journal of Lightwave Technology, 2016 A fast fiber-optic two-color pyrometer operating on the optical communication bands is designed for temperature measurements in machining processes. Off-the-shelf low-loss fiber-optic demultiplexers and optoelectronics equipment are used in order to obtain a cost-effective sensing solution while reducing both the temperature measurement error and the ...

Simulation of Laser Heating of Aluminum and Model Validation via Two-Color Pyrometer and Shape Assessment. [PDF]
Materials (Basel), 2018 The modeling of laser-based processes is increasingly addressed in a competitive environment for two main reasons: Preventing a trial-and-error approach to set the optimum processing conditions and non-destructive real-time control. In this frame, a thermal model for laser heating in the form of non-penetrative bead-on-plate welds of aluminum alloy ...

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
