Abstract
A method and system for measuring a sample property (X) by means of photonic circuit (). The photonic circuit () comprises at least two photonic sensors () configured to modulate the light according to respective output signals (S,S) with periodically recurring signal values (V, V). The photonic sensors () comprise a low range sensor () with a relatively low range or high sensitivity for measuring a change (ΔX) of the sample property (X) and a high range sensor () with a relatively high range or low sensitivity to measure the change (ΔX) of the sample property (X). The sample property (X) is calculated by combining the output signals (S, S) of the sensors (). Particularly, the second output signal (S) of the high range sensor () is used to distinguish between recurring signal values (V) in the first output signal (S) of the low range sensor ().
