Abstract
The present invention relates to optical sensor arrangements, especially sensors of the type that can be used in motor vehicles and which can detect hydrogen in a gaseous measured medium. According to the invention, an optical sensor arrangement has the at least one radiation source () for emitting radiation, the at least one measuring transducer which modifies its optical characteristics in response to the presence and/or concentration of at least one analyte in a measured medium () and is arranged so that it interacts with at least part of the emitted radiation (), a first detector unit () for capturing a change in radiant intensity due to the changed optical characteristics of the measuring transducer and for outputting a first measuring signal and a light conducting body () which is transparent to the emitted radiation, wherein the measuring transducer, which is sensitive to the analyte, is arranged on at least one surface of the light conducting body () so that the emitted radiation impinges on a surface of the measuring transducer which faces away from the measured medium ().
