Abstract: A sensing system and method for sensing a component in a liquid is disclosed. The system comprises a microfluidic channel, the microfluidic channel comprising a first end and a second end, wherein the microfluidic channel is open at the first end and closed at the second end. The system also comprises at least one measurement sensor positioned adjacent the first end, the measurement sensor being arranged for detecting a measurement signal and a reference sensor positioned in the microfluidic channel adjacent the second end, the reference sensor being arranged for detecting a reference signal of the liquid. The system further is configured for combining the measurement signal and the reference signal so as to filter out background influences.

Abstract: An integrated wavelength-selective filter device comprises a first optical element, for directing received radiation into a direction defined by a first angle, and a second optical element being a diffractive element configured for diffracting the directed radiation under a second angle. The second angle is such that for a single reference wavelength the diffracted radiation is directed into a propagation medium for advancing therein towards a predetermined position on the first optical element or on a further optical element for filtering radiation having a wavelength substantially matching the reference wavelength from radiation having a substantially different wavelength. The propagation medium is formed from a material that is different from any material of the substrate of the first and the second optical element.
