For distributed temperature sensing often a code correlation technology [2] [3] [4] is employed which carries elements from both principles. OTDR was developed more than 20 years ago and has become the industry standard for telecom loss measurements which detects the—compared to Raman signal very dominant— Rayleigh backscattering signals.
[8] [9] The fiber-optic sensor is well suited for this environment as it functions at temperatures too high for semiconductor sensors (distributed temperature sensing). Optical fibers can be made into interferometric sensors such as fiber-optic gyroscopes , which are used in the Boeing 767 and in some car models (for navigation purposes).
Distributed fiber-optic sensing technology can be used for leak detection through DAS and DTS. [26] AP Sensing has a regional office in Bahrain , and operates throughout the Middle East . [ 27 ] Their Distributed Fibre Optic Sensing is designed to monitor pipeline leaks, and is used by the Kuwait Oil Company and the Abu Dhabi National Oil Company .

Situated only an hour and a half from Austin, Fredericksburg has long been the cultural heart of the Texas Hill Country, influenced by the German pioneers who settled there over 175 years ago.Now ...
The Wizards are 2-2 when shooting over 40% from deep this season. There may be hope yet. NBA rewind: Warriors' losing streak hits five games; Mavericks are surging
Another possibility to minimize the temperature dependence of a heat flux sensor, is to use a resistance network with an incorporated thermistor. The temperature dependence of the thermistor will balance the temperature dependence of the thermopile. Another factor that determines heat flux sensor behavior, is the construction of the sensor.
