    Abstract: A sensor that determines information related to a gaseous analyte in a body of fluid. The sensor comprises an emitter, a luminescable medium, a radiation sensor, and a processor. The emitter emits electromagnetic radiation having an oscillating intensity. The luminescable medium communicates with the body of fluid and emits luminescent radiation in response to the received electromagnetic radiation. The radiation sensor receives the luminescent radiation, and generates an output signal based on the intensity of the received luminescent radiation. The processor samples the output signal generated by the radiation sensor at two or more predetermined periodic points over the oscillation of the intensity of the electromagnetic radiation to determine information from the samples related to a phase difference between the oscillation of the intensity of the electromagnetic radiation emitted by the emitter and oscillation of the intensity of the luminescent radiation received by the radiation sensor.

    Abstract: The invention relates to a method for measuring a concentration of a gas in a gas mixture, said method comprising that: a light beam modulated in a ramp shape and/or in a step shape in its wavelength and additionally periodically modulated, in particular in its wavelength, is transmitted from a light source, in particular a laser, into a measurement zone; the modulated light beam passes through a gas mixture in the measurement zone and is detected as reception light by a detector, wherein the reception light is converted by the detector into a detector signal; a derivative signal is determined based on the detector signal by performing a transformation of the detector signal into the frequency range, in particular by a Fourier transform of the detector signal, wherein an evaluation of the detector signal transformed into the frequency range is performed, in particular only, for an n-fold of the frequency of the modulated light beam in order to obtain the derivative signal; and at least two measurement values of a phase of the derivative signal are determined and a correction function is calculated based on the determined measurement values of the phase of the derivative signal in order to correct the derivative signal with the correction function.
