发明名称 Verfahren und Vorrichtung zur Bestimmung eines Lichttransportparameters und eines Analyten in einer biologischen Matrix
摘要 The invention relates to a method for selectively determining the index of dispersion mu <sb>s </sb>in a biological dispersion matrix, especially for the non-invasive determination of the concentration of glucose in the skin, with the aid of detection measuring, whereby respective light is radiated as a primary light (9) in the biological matrix (5) and measurement occurs for an intensity measuring value of exposed secondary light (12) exiting from a detection point (33-40), which is disposed at various measuring distances ( rho ) from the respective point of radiation (10) during said detection measurements. In order to improve the quality and selectivity of the determination of mu <sb>s</sb>, the primary light is radiated by means of a contacting light guiding element at an oblique angle of between 5 DEG and 85 DEG . At least two detection measurements of the measuring interval ( rho ) between the respective radiation point (10) and the respective detection point (33-40) corresponds to a maximum five fold value of the average path length of the propagating light in the biological matrix.
