    Abstract: Characteristics of a flame within a turbine or burner are determined based upon ultraviolet, visible, and infrared measurements of the flame. The measurements include a measurement of the amplitute of frequency bands that are indicative of an efficient combustion process, such as those that increase when the flame temperature increases. The measurements also include of the amplitude of frequency bands that are indicative of an inefficient combustion process, such as those that do not vary, increase a relatively small amount, or decrease when the flame temperature increases. The temperature of the flame may therefore be determined accurately, to facilitate efficient operation of the turbine or burner while minimizing polluting emissions. A fiber structure, suitable for remote location of sensors and processing equipment passes energy for several spectra by providing a hollow core that passes infrared energy, in combination with a core of visible-transmissive material that passes visible or ultraviolet energy. Contaminants in the turbine or burner are detected, and a degree of contamination measured, by detection of energy levels for particular wavelengths associated with a respective contaminant.

    Abstract: A method of measuring the temperature of a remote body which comprises determining the frequency range to be covered and the portion of that range or frequency band to be covered by each detector of a detector array or by a single detector via a filter for applying different frequency bands to the single detector. The required detector or detectors are then provided and sense the energy radiated by the remote body whose temperature is to be measured. The detector or detectors then provide an output of the amount of energy measured in each unique frequency band and sends these measured outputs to a processor. The processor receives the measured outputs from the detector(s) and determines therefrom in accordance with an algorithm thereat the measured temperature. The processor then provides an output indicative of the measured temperature.
