摘要：The invention relates to a method and to a device for using partially non-stabilized broadband light sources to accurately measure partially broadband-absorbingsubstances using referencing measuring cells. In order to create a low-cost, high-resolution, and at the same time fast spectrographic device for measuring concentrationsof substances in fluid or gaseous media that is also suitable for harsh environments, thelight radiated by the broadband light sources (1) through light guiding optical systems isfed through the measuring section of the self-referencing measuring cell (20, 30, 40) oronly partially through a measuring cell (10) to a measurement detector (photoreceptor11) and partially through a reference path (optical waveguide 8) to a reference detector(photoreceptor 15), and a mode coupler (5, 9, 14) is associated with each opticalwaveguide (2, 4, 7, 8) in order to homogenize the radiation characteristic of thebroadband light sources (1), which varies over time and space.
