    摘要： The invention relates to a system (101) for monitoring a position of a distal end (102) of a tube (104) with respect to a blood vessel (106) of a mamma. The system comprises a source (110) for generating an outgoing beam (112) of electromagnetic radiation having a predefined electromagnetic spectrum. The system furthermore comprises a guideway (114) for guiding the outgoing beam to the distal end, and for guiding an incoming beam (116) of electromagnetic radiation reflected by surroundings of the distal end in response to said outgoing beam to a measurement arrangement (120) which is arranged for measuring a parameter (122) associated with an electromagnetic spectrum of the incoming beam. The system furthermore comprises a comparator arrangement (124) for comparing said parameter with a reference parameter (126) associated with a reference electromagnetic spectrum representing a predefined location of the distal end inside the mammal.

    摘要： The present invention provides an optical fiber for connecting a probe head and a base station of a spectroscopic analysis system for analyzing the molecular composition of a volume of interest. The optical fiber comprises a core for transmission of excitation radiation from the base station to the probe head and a first cladding for transmission of multi-mode return radiation from the probe head to a spectroscopic analysis unit of the base station. Preferably, the first cladding is surrounded by a second cladding and therefore provides a multi-mode wave guide by itself. Appropriately designing the dimensions of the core, the first cladding and the second cladding provides an optimal collection and coupling efficiency of the optical fiber. Coating of the distal end facet of the optical fiber with multi-layer optical filters allows an effective separation of elastically and inelastically scattered radiation which is of advantage for the spectroscopic analysis.

    摘要： The invention relates to an identification method carried out as follows. A surface structure and an inner structure of a body member are measured (ST1-ST4, ST7) so as to obtain a surface-structure measurement result (FPM) and an inner-structure measurement result (BVPM), respectively. The surface-structure measurement result (FPM) is compared (ST5) with a surface-structure reference result (FPR) that distinguishes an individual from other individuals. The inner-structure measurement result (BVPM) is compared (ST8) with an inner-structure reference result (BVPR) that is associated with the same individual and that distinguishes the individual from other individuals. The body member may be, for example, a finger. In that case, the surface structure comprises a fingerprint and the inner structure comprises a blood-vessel pattern.

    摘要： An autofocus mechanism for a spectroscopic system determines a time varying optical property of a volume of interest. The mechanism measures the fluctuations of the optical property of the volume of interest for determining the position of the volume of interest. The spectroscopic system focuses an excitation beam into the determined volume of interest and collects return radiation emanating from the volume of interest for spectroscopic analysis. Preferably, inelastically scattered radiation of an excitation beam is separated from elastically scattered radiation for spectroscopic analysis. The elastically scattered radiation of the excitation beam is measured for fluctuations of the optical property of the volume of interest. A control loop maximizes the amplitude and/or intensity of the fluctuations and specifies the position of a volume of interest e.g. the center of a capillary vessel.
