A sensor used to measure temperature or concentration of a combustible gas. The sensor includes an optical head that picks up infrared information emitted by the combustible gas. The infrared information is conveyed from the optical sensor through a diffracting device onto a strip of photodetectors. A processor receives the information garnered by the photodetectors and determines the concentration and temperature profile of the combustible gas based on a stored thermodynamic model, radiation behavior, varying the thermodynamic parameters, and comparing a calculated spectrum with the measured spectrum. The sensor additionally has elements, such as cooling devices and casing to make it suitable for use with aviation where altitude creates problems with known methods of gas temperature analysis.
