PPT-Optical Thermometry

Haiqing Guo Dept of Fire Protection Engineering hguoumdedu Lab Methods Day June 25 2014 Introduction Optical thermometry ie soot pyrometry provides soot temperature and soot concentration information in flames . The process of OCR involves several steps including segmentation feature extraction and classification Each of these steps is a field unto itself and is described briefly here in the context of a Matlab implementation of OCR One example of OCR is sh Sostmann 1 THE ABSOLUTE OR THERMODYNAMIC KELVIN TEMPERATURE SCALE Temperature is a measure of the hotness of something For a measure to be rational and useful between people there must be agreement on a scale of numerical values the most familiar of For example if two di57372erent sized containers 64257lled with di57372erent gasses at di57372erent pressures and temperatures are brought into thermal contact after a period of time the 64257nal volumes pressures entropies enthalpies and other ther However unlike electrical current that 64258ows through a metal strip according to Ohms law optical waves travel in the waveguide in distinct opti cal modes A mode in this sense is a spatial distribution of optical energy in one or more dimensions t 0600 polarised. emission in X-ray binaries.
