Abstract: The invention relates to an application device for a sensor head, which can be used for example as a component of a measuring arrangement for obtaining measurement signals from living tissue in order to determine the presence, concentration, or material composition of bodily fluids and substances possibly only temporarily vessel-bound. The aim of the invention is to create solutions by means of which it is possible to take non-invasive measurements, in particular spectrometric measurements, in a manner that is advantageous in terms of measurement and ergonomics, in the region of the fingers of a user, in particular a patient.

Abstract: The invention relates to a measuring device comprising a light source device (Q1, Q2), a spectrometer device (1) and a measuring head structure (2), the measuring head structure being coupled with the light source device via a first optical waveguide (L1) and a second optical waveguide (L2) as well as with the spectrometer device via a third optical waveguide (L3), said optical waveguides leading to a contact surface provided by the measuring head structure. The outlet positions of the optical waveguides are adapted to each other such that the distances (a,b) of the outlet positions of the first and second optical waveguides are different from the outlet position of the third optical waveguide. In this manner, a measuring device is devised which is characterized in that it is highly insensitive to disturbing influences which due to the uneven scattering of the cell structures occur in vital tissue systems.

Abstract: The invention relates to a method and a measuring instrument for collecting spectrometric test signals from living tissue. The aim of the invention is to create solutions which make it possible to generate, in the course of a spectrometric measurement, test results that supply more comprehensive data than previously known recording attempts. Said aim is achieved by a method for generating spectrometric test signals, in which light (L) is injected into a living tissue area (G) to be examined, reflected light (R) emerging from the tissue area to be examined is fed to a spectrometer device, and test signals representing the intensity of the reflected light by associating the same with the wavelength are generated by means of the spectrometer device.

Abstract: The invention relates to a method and device for the detection, in particular for determining the concentration, of substances in vital tissue. The object of the invention is to create a method and device for the detection of substances in vital tissue, this permitting the reliable qualitative and quantitative detection of such substances in a physiologically safe manner. The object of the invention is achieved by a method for the detection of substances in vital tissue in which light of a predetermined wavelength is directed onto the tissue in such a manner that the light penetrates into the tissue; at least some of the light escaping from the tissue is captured and the reflected light is analyzed with an association being made between its wavelength and intensity; and the thus determined properties of the reflected light are compared with at least one reference system, the presence and/or concentration of a substance being deduced on the basis of a correlation with the reference system.

Abstract: The invention relates to a process and a device for recognition and in particular quantification of a medium fraction in a translucent solution, in particular in a motor fuel. According to the invention, a process is proposed for recognition of the concentration of a fluorescent substance, in particular a marker, in a fluid to be examined in which a sample has been introduced into an examination space, in connection with an exposure step the examination space is trans-illuminated by a beam of light such that in the examination space one fluid segment interspersed by a beam of light and one fluid segment not interspersed by a beam of light are formed.
