  • Patent number: 12208192
    Abstract: A method and device for monitoring a measurement object. A passive unit has a light source, which radiates radiated light modulated by at least one external measurement influence from the measurement object. An active unit has an optical detector, which receives the radiated and modulated light via an optical link. In addition, there is a transmitter unit emitting energy, such as optical energy, sound energy, electromagnetic energy etc. The emitted energy is coded by an energy signature and sent to the passive unit via an energy link. The passive unit receives the emitted energy by a receiver unit, which decodes the energy signature and moderates the radiated and modulated light in dependence of the energy signature. The received energy is also used to drive the light source. A processor unit may decode the signal for discriminating the signal from error sources.

  • Patent number: 11604142
    Abstract: A device for monitoring a measurement object, comprising: an active unit having a light source emitting light with a wavelength spectrum and an optical detector. An optical link passes the emitted light to a at least one passive unit. Each passive unit comprises a sensor and a selector for diverting the emitted light to the sensor. The sensor comprises a luminescent material being directly or indirectly affected by the emitted light diverted by the selector. The sensor is sensitive to an external influence by the measurement object for producing a modulated signal, which is passed to said detector via the optical link. The luminescent material may be a fluorescent material, which is directly irradiated by the emitted light from the light source.
