The Optical fiber DTS (Distribution
Temperature Systems) are unique distributed temperature
systems using optical fiber as a sensor. These systems are
able to measure the temperature along the fiber, in some
case they can measure tension as well. For their function
they use nonlinear effect in optical fiber (Raman
nonlinear effect, Brillouin nonlinear effect). The greatest
advantage of this sensor system is just using of the optical
fiber (electromagnetic resistance, small size, safety using
in inflammable and explosive area, easy installation,
etc.). The Optical fiber DTS systems can be used with
advantage even in areas, where the using of classic
sensors would be problematic. The typical example is
monitoring of outflows in pipelines, illegal service
connection etc. In some processes it is necessary to know
the exact temperature (tension) in particular points.
There it can appear a problem with resolution of the
optical-fiber DTS. This article deals with problems of the
optical meanders implementation into the building
processes.
