Spectral Remote Sensing Of The Dynamic Temperature Distribution In Glass Plates

Dynamic temperature distributions in 3.71, 6.76 and 11.68mm thick float glass test plates were experimentally determined using both the spectral remote sensing method and thermocouples fused in the plates. Measurements were made while the test plates cooled from approx. 550C, by radiation and natural convection in the laboratory ambient. Temperatures determined using the spectral remote sensing method are compared with those from the thermocouples fused in the glass and with theoretical predictions to demonstrate the accuracy and limitations of the spectral method.
