A detection system includes flame sources at least two of which are independently controllable; photodetectors each having an independent view of the flame sources and being capable of producing a respective current signal in response to flames produced by the flame sources; and a device for analyzing the current signals to determine state values of a plurality of state variables and transform the state values into at least one parameter value. A number of the flame sources is at least as high as a number of the state variables, and a number of the photodetectors is at least as high as the number of the state variables. In one embodiment, the flame sources include gas burners in a gas combustion chamber, the photodetectors include silicon carbide photodiodes, and the parameter value is representative of fuel rate, temperature, acoustic dynamics, nitrogen oxide concentration, or carbon monoxide concentration. The device for analyzing the current signals can include means for mapping each of the current signals with respect to the state variables and inversely mapping the current signals and the state variables to determine the dependence of each of the state variables with respect to the current signals.
