Many land and undersea oil operations rely heavily on temperature sensing for improved safety and functionality in harsh environments. Silica-based optical fibers have been increasingly used for distributed temperature and acoustic sensing applications….In recent work, OFS performed an experimental
NKT Photonics is introducing the Koheras HARMONIK system: A high-power, frequency-converted and ultra-low noise laser system offering up to 7 W output. With a market leading low phase noise and narrow linewidth at 775-780 nm, it is ideal for ultracold atom applications.
For intrusion detection, OptaSense uses a distributed acoustic sensing setup that analyzes the Rayleigh scattering....The strain signature of a fiber-optic cable around 50 km long can be deconvolved to detect movement at distances of around 10 m from the fiber with a 1 m accuracy.
Focus, a leading German business magazine, ranked AP Sensing as one of its Top Employers of 2019. AP Sensing achieved the outstanding position of 11th in the industry segment of ‘machinery and equipment,' an important industry in Germany. The survey ranked 750,000 German companies.
At the Lawrence Berkeley National Laboratory, Dr. Jonathan Ajo-Franklin is using dark fiber to measure seismic signals. Dr. Ajo-Franklin’s team gained permission to access a section of a dark fiber network between Sacramento and Calusa, California.
