Abstract

Infrared transmitting heavy metal fluoride optical fiber has been used to separate an FTIR analyzer from a remote measurement point. Several types of remote sensors have been developed for species concentration measurements. Remote transmission cells connected to fiber cables have been used for the measurement of spectra of liquids and gases. Evanescent wave probes have been developed to obtain spectra in highly absorbing and highly scattering media. Remote spectra taken with an FTIR fiber-optic analyzer in the 8000 - 2000 cm1 spectral region are presented. A calculation of detectability limits for these species based on the measured data will be presented. A discussion of sensor multiplexing applied to remote fiber optic FTIR spectroscopy will be given.
