The principle and analysis of accuracy of a two-color-emission-CT pyrometer
International Congress on Instrumentation in Aerospace Simulation Facilitie, 2003An algorithm of a two-color-emission-CT (computed tomography) pyrometer is presented, and the measured values of temperature and density of burnt gases are discussed. The greatest advantage of this method is that it needs no blackbody as a reference source and only one window for each light path.

Investigation of Temperature at Tool-Chip Interface in Turning Using Two-Color Pyrometer
Journal of Manufacturing Science and Engineering, 2002A technique for measuring temperature at the interface between a cutting tool and a chip is developed. A two-color pyrometer with fused fiber coupler is applied to the temperature measurement of the tool-chip interface in dry and wet turning. By using this pyrometer, it is possible to measure the temperature of a very small object without emissivity ...

A new wavelength selection criterion for two-color pyrometer interfered with participating media
Infrared Physics & Technology, 2018Abstract Two-color pyrometry is well established and widely applied to surface temperature measurements. However, its accuracy degrades significantly when the transmission path between the object surface and the pyrometer is full of high concentration participating media, which attenuates the surface radiation signal to the pyrometer.

Reduction of methodological errors in determining the temperature of metals by two-color pyrometers
Journal of Engineering Physics and Thermophysics, 2006Two-color methods of optical control of the thermodynamic temperature of metals subjected to thermal treatment are analyzed. A technique for taking into account the nonmonochromaticity of the photoreception path is suggested and an analysis of methodological errors of two-color pyrometers with wide spectral ranges is performed by numerical simulation.

Review of Scientific Instruments, 2019
The design of a two-color pyrometer is described, allowing not only measurement of the temperature of a single flying luminous particle with sizes from submicron to millimeters but also the 3D reconstruction of its flight trajectory, the determination of its real velocity, size, frequencies of oscillations of its radiation intensities, and the type of ...

Near-infrared two-color pyrometer for determining ignition temperatures of metals and metal alloys
Review of Scientific Instruments, 1985A two-color pyrometer has been designed, constructed, and used to measure the ignition temperatures of metals and metal alloys. Cylindrical metal and metal alloy specimens were ignited by a focused cw CO2 laser beam in a cool, static, pure oxygen environment.

Review of Scientific Instruments, 1995
This article describes a new two-color pyrometer able to obtain multiple temperature reading using charge couple device type sensors. The device was tailored to fit the characteristics of self-propagating high-temperature synthesis processes in order to be able to detect temperature profiles and propagation rates of the combustion front.
