Abstract

A method for optimizing values of n detection wavelengths of an optical gas sensor configured to detect n different gases is provided, including: a) calculating a value of a determinant of an absorptivity matrix ε whose coefficients represent spectral absorptivity of each of the n different gases at the n detection wavelengths, the calculating being repeated several times, each time modifying at least one of said n detection wavelengths so the values of said n detection wavelengths are comprised within a range of values for which the spectral absorptivity of at least one of the n different gases is non-zero; and b) determining the values of said n detection wavelengths for which the calculated value of the determinant of the absorptivity matrix ε corresponds to a maximum calculated value amongst a set of values calculated in step a).
