| 摘要 |
A measuring instrument for determining the concentration of components in the body tissue by reflection spectroscopy is disclosed. In order, inter alia, to increase the functional reliability in the case of vibrations, the measuring instrument includes a diode laser with at least one laser diode and a waveguide structure, which has an external resonator, with a wavelength selective element, for each laser diode. In the process, the radiation generated by a laser diode is coupleable into the waveguide structure and the corresponding resonator and once again decoupleable from the resonator and the waveguide structure. Moreover, a corresponding method and a motor vehicle equipped therewith are disclosed. |
