摘要： A method and an arrangement for measuring the concentration of gases in a sample includes the generation of a monochromatic light beam having predetermined color characteristic. An indicator generates light signals indicative of the concentration of the gases in a sample to be measured and includes a light-transmissive surface positioned to be impinged by the monochromatic light beam, a diffusion membrane adapted to be placed in the proximity of a sample and being permeable to a selected gas component thereof, and an indicating substance positioned to be impinged by the monochromatic light beam penetrating the light-transmissive surface and by the gas component penetrating the diffusion membrane. The indicating substance reacts when illuminated by the incident monochromatic light by emitting a resultant light beam having an emitted component which has a color characteristic different from the predetermined color characteristic of the monochromatic light beam. The resultant light beam is conducted away from the indicating substance through the light-transmissive surface. Finally, the emitted component is discriminated from the resultant light beam so that the change in the color characteristic of the indicating substance can be measured and correlated with the concentration of gases in the sample.

摘要： A sensing arrangement for measuring physical parameters or concentration of particles is assembled of a laminar source of luminescent radiation. Fluorescent indicating particles are arranged in an indicator layer adjoining one major side of the laminar light source. The indicator layer adjoins a measuring space containing the object of measurement whose particles enter the indicator layer by diffusion. Fluorescent indicating particles are arranged in the indicator layer to emit fluorescent light when illuminated by the laminar light source. Photoelectric receiver is adjacent the opposite side of the laminar light source to measure the intensity of the fluorescent radiation. In a modification, luminescent phosphors and fluorescent particles are arranged in a common matrix.

摘要： To measure potential differences in second-class conductors without interference potentials, there are provided a potential generator cooperating with a potential-measuring structure. This structure includes a substrate of electrically highly insulating and chemically inert material embedding optical indicators whose optical properties change as a function of the applied electric potential difference. Both the potential generator and the potential-measuring structure have boundary surfaces which are in contact with the second-class conductor and opposite surfaces interconnected by an equalizing conductor. A light-measuring device is arranged for intercepting light changes in the indicators, thus measuring the potential difference.
