Abstract :
Precision in wavelength modulation spectroscopy measurements is quantified via Shannonpsilas information theory. The optimal harmonic detection order, yielding maximum information (in bits), is best obtained by quantitative considerations of the signal structure rather than those of conventional signal-to-noise ratios.
