Abstract

The invention relates to a method and arrangement for determining the optical spectral shift caused by physical or chemical effects. The object on which the invention is based, namely to specify a method and an arrangement realising the same, is achieved when with the aid of fibre-optic sensors and wavelength-dispersive modules and evaluation units and a suitable reference value formation a multiple spectral recording and determination of ratio is carried out, the result of which contains the value of the physical or chemical parameter to be determined.
