    摘要： The present invention provides a spectroscopic system and a transmission based imaging system for a spectroscopic system as well as a probe head for a transmission based imaging system for a spectroscopic system and a corresponding transmission based imaging method. The spectroscopic system is preferably applicable to in vivo noninvasive blood analysis. Transmission based imaging makes use of a transmitted portion of an imaging or monitoring beam that has been transmitted through biological tissue. By means of transmission based imaging, a contrast decreasing impact of scattered radiation can be effectively reduced. Additionally, by arranging the imaging light source opposite to an objective lens of the spectroscopic system, unintended propagation of spectroscopic excitation radiation into free space can be effectively prevented.

    摘要： The present invention provides a spectroscopic system (100) for determining of a property of a biological structure in a volume of interest (120) of a person. The spectroscopic system (100) comprises a low cost objective lens (118) for directing an excitation beam into a volume of interest (120) and for collecting return radiation (124) from the volume of interest (120). After detection of the return radiation (124), i.e. the spectroscopic signals, a correction unit (106) performs the compensation of the aberrations of the spectroscopic signals introduced by the low cost objective lens (118). Since the aberrations of the objective lens (118) strongly depend on the lateral distance (122) of the volume of interest (120) from the optical axis (116) of the objective lens (118), the correction unit (106) makes effective use of a correction table (110) providing an assignment between correction values and various lateral positions (122) of the volume of interest (120).

    摘要： The present invention provides a spectroscopic system for determining a property of a fluid flowing through a volume of interest underneath the surface of the skin of a patient. The spectroscopic system comprises a probe head that has at least an objective for directing an excitation beam into the volume of interest and for collecting return radiation. The spectroscopic system has further a base station having at least a spectroscopic analysis unit and a power supply. The system makes use of a beam combination unit, a filter unit and a focusing unit for combining and separating a variety of different optical signals and for precisely positioning the optical signals inside the volume of interest. The beam combination unit, the filter unit and the focusing unit can be variably implemented inside the probe head or inside the base station depending on a specific applications of the spectroscopic system, thereby allowing for a flexible and compact design of the probe head.

    摘要： The present invention provides an autofocus mechanism for a spectroscopic system that is adapted to determine a property of a volume of interest. The volume of interest has an optical property that varies with time. The invention provides measurement means that are adapted to measure the fluctuations of the optical property of the volume of interest for determining the position of the volume of interest. The spectroscopic system being further adapted to focus an excitation beam into the determined volume of interest and for collecting 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 in turn exploited in order to measure the fluctuations of the optical property of the volume of interest. Making use of a control loop allows for maximization of the amplitude and/or intensity of the fluctuation inherently specifying the position of a volume of interest e.g. the center of a capillary vessel.

    摘要： The present invention provides an optical analysis system for determining an amplitude of a principal component of an optical signal. The principal component is indicative of the concentration of a particular compound or various compounds of a substance that is subject to spectroscopic analysis. The optical signal is subject to wavelength selective weighting and wavelength selective spatial separation specified by a weighting function. The optical signal is preferably separated into two parts that corresponding to a positive and negative spectral band of the weighting function, respectively. The separation provides separate detection of the separated parts of the optical signal without significant loss of intensity, thereby providing an improved signal to noise ratio of the determined principal component. Separation and weighting of the optical signal is realized by two multivariate optical elements.
