摘要： A method for the analytical determination of the glucose concentration in a biological sample. In a detection step, light is irradiated into the sample and the light emerging therefrom after interaction with the sample emerges therefrom is detected in order to measure a physical light property affected by said interaction. The glucose concentration is determined from this measurement in an evaluation step. To provide a method for determining glucose in reagent-free and non-invasive manner, the invention proposes that a portion of the light emitted by the light source be guided along a reference light path of defined optical path length to the photodetector, that the total measuring light path also has a defined optical length and that the measuring light path after it has traversed the sample is so combined with the reference light path that the measuring light and the reference light interfere with each other. The photodetector measures an interference signal used in the evaluation step to determine the glucose concentration.

摘要： The invention concerns a method for investigating a scattering medium, especially a biological matrix, with intensity-modulated light. In order, in such a frequency-domain measuring procedure, to reduce the expenditure on electronics without restricting accuracy of measurement, a method is proposed, in which, in order to investigate a scattering medium, especially a biological matrix, with intensity-modulated light, a high-frequency modulation signal is generated by a frequency generator (18), the intensity of a light emitter (10) is modulated with a modulation signal and the light from the light emitter (10) is radiated into the medium, the modulation signal includes frequency chirps during which the modulation frequency is tuned from an initial frequency to a final frequency, the modulation signal is delivered from the frequency generator (18) via at least two different signal paths (23A, 24) to a signal mixer (31), so that during a frequency chirp the input signals of the signal mixer (31) differ by a differential frequency whose magnitude is a function of the difference between the signal transit times over the at least two signal paths (23A, 24) and of the rate of change of the modulation frequency, wherein at least one of the signal paths includes a light path section (20A) passing through the medium as a measurement signal path (23A), and the output signal of the signal mixer (31) is further processed to produce information relating to the scattering medium (FIG. 2).

摘要： Method for determining an analyte in a scattering matrix. In a detection step detection measurements are made in which light is irradiated into the matrix as primary light and light leaving the scattering matrix is detected as secondary light, in order to determine as a measurement quantity a measurable physical property of the light which is variable due to the interaction of the light with the matrix. Information on the presence of the analyte in the matrix is determined in an evaluation step. The determination of optically weakly absorbing analytes against a strongly absorbing interference background is improved by the use of two selection methods for the depth selective detection of the secondary light in combination with one another. Primary light is focused by means of a primary light optically focussing element onto a region of focus lying in the matrix at a predetermined measuring depth and the region of focus is imaged by means of a secondary light optically focusing element onto a light entry aperture arranged in the light path of the secondary light to the detector. In addition to this first depth selection by a confocal arrangement, a second depth selection device is used to detect light reflected from a defined measuring depth as secondary light, with the measuring depth coinciding with the depth of focus.

摘要： A method and an apparatus for determining analytical data concerning the inside of a scattering matrix, in particular of a biological sample. In a detection step detection measurements are carried out in which light is irradiated into the matrix as primary light at an irradiation site (12) through an interface bounding the scattering matrix (6) and light emerging out of the scattering matrix through the interface is detected as secondary light at a detection site (13) at a predetermined measuring distance from the irradiation site, in order to determine as a measurement variable a measurable physical property of the light which varies due to the interaction of the light with the scattering matrix, which measurement variable is a measure of the analytical data to be determined. In an evaluation step the analytical data are determined on the basis of the measurement variable measured in the detection step. In order that such a matrix analysis may be carried out with relatively simple measuring means, at least two detection measurements are carried out in the detection step with different reflection conditions at the interface (5) between the irradiation site (12) and the detection site (13), in each of which the measurement value of the measurement variable is determined.

摘要： A method and apparatus for analytical determination of a concentration of an analyte in a biological sample include a series of hardware elements and method steps which perform at least two detection measurements, with each detection measurement including the step of irradiating light at an irradiation site as primary light into the biological sample through a boundary surface. The light is propagated along a light path, and light is detected as it emerges from the biological sample as secondary light through a detection site. The irradiation site and detection site are separated by a measuring distance. At least two detection measurements are performed with at least two different measurement light paths between the irradiation site and the detection site. Each of the detection measurements is a frequency-domain spectroscopic measurement which is performed at at least two different wavelengths of light, and includes a comparison of a phase shift of the secondary light with the primary light as a first measurement variable, and an intensity of the secondary light as a second measurement variable. The method also includes the steps of determining the analyte concentration based upon the first and second measurement variables.

摘要： Method and apparatus for the analytical determination of glucose concentration in a biological matrix, wherein in a detection step light from a light emitter is irradiated into the biological matrix as primary light via a boundary surface of the biological matrix and light emerging from the the biological matrix through a boundary surface is being detected by a light detector in order to determine a measurable physical light property which is changed by interaction with the biological matrix and which correlates with the glucose concentration of said matrix. The glucose concentration is ascertained in an evaluation step on the basis of said change of the physical light property determined in at least one detection step in comparison with a calibration. In order to achieve by such a method good analytical accuracy in reagent-free and non-invasive manner, for instance to observe the change of the concentration of the analyzed substance (monitoring) over an adequate time interval, a measurable parameter corresponding to the light transit-time within the biological matrix between a defined irradiation site and a defined detection site and correlating with the glucose concentration is determined in the detection step.
