particular case of low-cost sensing applications, frequency-domain measurements pres-
ent some considerable advantages. Frequency-domain measurements are usually faster;
the sinusoidal signals are easier to measure than the very short decay signals character-
istic of time-domain measurements; no deconvolution is necessary, saving computation
time and money in complex analyses soware. Overall, considering specic applica-
tions, frequency-domain systems can usually be implemented with simpler electronics
and at lower cost than time-domain systems. Nevertheless, luminescent emission can
sometimes be too weak ...
