Abstract

Many industrial processes or other phenomena of interest cannot be measured with conventional instruments because they are too hot, too cold, highly radioactive, or other-wise inaccessible to direct observation. Nuclear wastes stored in underground repositories, for example, will require in-situ monitoring. A new technology that uses long distance fiber optics to transmit laser-excited fluorescence now makes it possible to remotely monitor such installations via optical fiber cables at distances up to one kilometer. The applications are listed below. - Sampling of remote locations - Multipoint sampling with single instrument - Measurements in inaccessible locations - Coping with aggressive environments - Avoiding contamination - Continuous monitoring
