Review of Scientific Instruments, 2001
A two-color pyrometer has been developed to measure the temperature of surfaces with unknown emissivities during high speed turning processes. Quartz fibers enable measurements at locations with limited optical access. The sensitivity of the pyrometer has to be high enough to measure temperatures down to 300 °C of an aluminum alloy with an emissivity ...

AIP Conference Proceedings, 2003
A two‐color pyrometer has been developed to measure the temperature of metallic surfaces with unknown or varying emissivities in manufacturing processes, e. g. the chip temperature during turning. The absolute temperature uncertainty has been analyzed for metallic surfaces with various surface properties for the pyrometer wavelengths 1.7 and 2.0 μm ...

Volume 5: Energy Storage; Fans and Blowers; Heat Transfer: Combustors; Heat Transfer: Film Cooling
Abstract This study used a non-invasive two-color pyrometry to investigate transpiration cooling and film cooling on a flat-plate model. Unlike typical infrared thermography, this technique is not affected by changes in emissivity due to heating.

Review of Scientific Instruments, 2020
Two high-temperature 2D-pyrometers are described in this work. They are, respectively, based on the comparison of light intensities received by two monochrome cameras with narrow filters and the different color channels in a single color camera. The calibration procedure includes tests with thermocouples in flame flue gases and with a light bulb ...

Journal of Thermal Spray Technology, 2002
Advances in digital imaging technology have enabled the development of sensors that can measure the temperature and velocity of individual thermal spray particles over a large volume of the spray plume simultaneously using imaging pyrometry (IP) and particle streak velocimetry (PSV).
