- Abstract:
- Enormous technological progress in optical fibers for telecommunications has promoted the use of functional grids, mainly in sensor technology. To date, optical sensors with micro-structured Bragg gratings in the core of crystal fibers have been principally used in laboratories, however, there have also been first practical applications. In this paper, HBM’s own practical and theoretical investigations are presented as well as product development based on photonic Bragg sensors. The paper discusses strain and temperature related influences in conjunction with dynamically induced Bragg gratings in optical single-mode fibers and stress-induced interference on the grid.
New products from HBM such as special software modules and hardware components for signal processing of photonic sensors linking electrical and optical systems are briefly introduced at the end of the paper, as well as potential of high strain level applications will be demonstrated. - Keywords:
