Applications Of IR-Fibers In Remote Gas-Spectroscopy

Applications of infrared transmitting fibers in the field of gas sensing devices are reviewed with particular emphasis to fluorozirconate materials. Promising performance parameters of IR-fiber-optical detection schemes are discussed in comparison to conventional techniques. Fibre requirements regarding geometrical data, spectral attenuation, mechanical as well as environmental durability for future applications are summarized. Currently available fluorozirconate fibers have been experimentally characterized. Methane and carbon dioxid have been remotely measured using IR-fibers coupled to a Fourier spectrometer.
