SENSOR SYSTEM USING A HOLLOW WAVEGUIDE

摘要

The present application provides a method for determining one or two parameters of a sensor system for detecting a gaseous sample. The sensor system comprises a light source to generate a light beam, a hollow waveguide to receive the light beam and the gaseous sample, and a detector to detect an absorption peak of the gaseous sample, where the length and inner diameter of the hollow waveguide satisfy relationships as disclosed herein.
