An optical fibre Bragg grating (FBG) based strain sensor network incorporated in a functionalized textile-based carbon structure (FTCS) that can be used for structural health monitoring (SHM) is introduced. The aim of the design is not only to monitor strain, but also to act as a structural strengthening mechanism in the target application. The integration of the optical fiber, i.e. incorporating...
The work introduces textile based carbon structures that are functionalized with optical fibre sensors for structural health monitoring (SHM) of concrete based composites. The concept of the functionalized carbon reinforcement structure is shown in Fig. 1a. The optical fibre (that contains the sensors) is integrated directly during the manufacturing of the carbon reinforcement structure. Due to the...
An implantable Fabry-Pérot interferometer based pressure sensor is developed. The pressure sensor could be integrated directly onto the inlet shell of a left ventricular assist device (LVAD) to monitor blood pressure in real-time and provide a feedback control signal to achieve the optimal operation of LVAD. The diaphragm of the pressure sensor is made out of biocompatible polymer parylene-C.
We report a radio-over-fibre system for all-optical routing OFDM signal at 18.3 GHz over 950 m multi-mode fibre, with error vector magnitude penalty <3%.
We present, both numerically and experimentally, the nonlinearity effect of the intensity modulator in RoF transmitters through the comparison between single-carrier QAM and multi-carrier OFDM signals. The acceptable RF power level of the multi-carrier OFDM signal is 2 dB less compared with the single-carrier signal for the same EVM penalty of 1%, indicating the degradation due to inter-modulation...
Advanced optically-emulated x-QAM techniques and the modal dispersion-robust radio-over-fiber OFM technique enable the delivery of high-capacity data via a single multimode (silica or polymer) optical fiber in-building network to wired as well as wireless terminals.
