Sensitivity of Fabry-Perot Resonator Based Measurements of Gas Absorptions
In order to reach maximum sensitivity of gas attenuation measurements and to propose optimal parameters of the new developed spectrometer,the coupling characteristics of several resonator based measurement approaches were analyzed.Three types of resonator feed were investigated the first based on a radial feeding of a resonator cavity,second one using axially alignment feeding with two ports(transmission measurement)and the last having one axial port feeding(reflection measurement method).Based on both analytically derived relations and results form simulations,the optimal setting of coupling is proposed in the paper.Analytical results covering a wide range of couplings were validated by spectroscopic measurements of particular gases attenuations.
