Abstract: A spectroscopic apparatus, a method of determining a concentration and/or spatial gradient of an analyte of a bodily fluid and a corresponding computer program product are provided. The spectroscopic apparatus provides determination of a position of a capillary vessel (104) within a biological sample in order to focus spectroscopic excitation radiation to a volume (122). that is in close proximity to the capillary vessel but does not overlap with the capillary vessel. The provided apparatus, method, and computer program product advantageously exploit the permeability of the vessel wall with respect to an analyte that is subject to analyte concentration determination. By means of biological transport processes, the concentration of an analyte of a bodily fluid located in the capillary vessel influences the concentration in the surrounding of the capillary vessel. Spectroscopic analysis of a volume outside the capillary vessel can therefore serve for a precise and reliable analyte concentration determination inside the capillary vessel.

Abstract: The apparatus for measuring concentrations of fuel mixtures using depth-resolved laser-induced fluorescence is a fluorometer equipped with a sample container holder that is movable in the path of the beam from the light source. Fluorescent emissions from the sample mixture pass at 90° to the excitation light path through a slit that is narrow enough that the emission intensity is effectively produced by a thin layer of the sample and focused on a monochromator, with successive thin layers receiving nonuniform excitation radiation due to reduction of intensity along the excitation light source path with increasing depth penetration and due to reabsorption of emitted fluorescence from adjacent layers. The method has a first mode in which the emission spectrum is scanned at a fixed depth, and a second mode in which the sample is moved relative to the emission monochromator slit to vary the depth while keeping the emission wavelength fixed.

Abstract: To determine spectra, integrated multiple illuminant measurements from a non-fully illuminant populated color sensor may be converted into a fully populated spectral curve using a reference database. The reference database is partitioned into a plurality of clusters, and an appropriate centroid is determined for each cluster by, for example, vector quantization. Training samples that form the reference database may be assigned to the clusters by comparing the Euclidean distance between the centroids and the sample under consideration, and assigning each sample to the cluster having the centroid with the shortest Euclidean distance. When all training samples have been assigned, the resulting structure is stored as the reference database. When reconstructing the spectra for new measurements from the sensor, the Euclidean distances between actual color samples under measurement and each cluster centroid are measured. The spectra are then reconstructed using only the training samples from the cluster corresponding to the shortest Euclidean distance, resulting in improved speed and accuracy.

Abstract: Multivariate optical analysis systems employ multivariate optical elements and utilize multivariate optical computing methods to determine information about a product carried by light reflected from or transmitted through the product. One method of processing and monitoring the product includes introducing the product at an inspection point; illuminating the product with a spectral-specific light though an optic lens; directing the light that has passed through at least a section of the product through at least one multivariate optical element to produce a first signal, the directed light carrying information about the product; detecting the first signal at a first detector; deflecting a portion of the directed light to produce a second signal in a direction of a second detector, the second detector configured to detect the second signal; and determining at least one property of the product at a rate of about one section of the product per second to about five sections of the product per second based upon the detector outputs.
