| description | - 13 Abstract The present invention relates to a measuring-device for determining the concentration of body tissue contents by reflection spectroscopy. In order, among other things, to increase the device's functional reliability when subjected to shocks, 5 the inventive measuring-device comprises: a diode laser (1) with at least one laser diode (Ia, I b); and a waveguide structure (2), with an external resonator (2a, 2b) for each laser diode (I a, I b). Each external resonator (2a, 2b) has a wavelength-selection element. The radiation produced by a laser diode (Ia, I b) can be coupled into the waveguide structure (2) and the corresponding resonator (2a, 2b), and can be coupled 10 out of the resonator (2a, 2b) and the waveguide structure (2) again. The present invention also relates to a corresponding method and to a vehicle equipped with the inventive measuring-device. (Figure 1) 06/09/11,19396 speci, 13 |
