“…easy to operation, high sensitivity, long lifetime, immune to electromagnetic field, remote sensor, etc. In the recent years, flow-rate measurement using optical fiber devices has been reported based on the blades of the turbine adjusting the strength of the reflected light [8,9], important progress has been made in optical fiber flow sensors. But most of them are difficult for practical application due to the complex and immature measuring techniques and the high cost.…”

Abstract.A novel paddlewheel flow sensor has been developed which based on a hydrophobic fibre-optic pick-up is designed in this paper, it presents the theory, operation principle, design of the sensor. The hydrophobic fiber optic head is the sensing part, which can provide two different reflective signals output by rotation of rotor, light pulse frequency is proportional to the flow-rate. Signal acquisition and processing is realized based on LabVIEW, the information of signal waveform and flow velocity in a pulse time can be processed and displayed on the front panel real time. The flow sensor provides a completely passive measuring system for gas and liquid flows, it is rather cheap and inherently safe. The detector unit can provide either a pulse output or convert the signal into flow units. Preliminary experimental testing on the flow sensor has been carried out, the results confirmed that the design is feasible.

“…Over the past years, the use of fiber-optics-based sensors have increased [ 1 ] due to the fact they offer: (1) immunity to electromagnetic interference; (2) immunity to radio frequency interference; and (3) electrical isolation. Moreover, their use in applications for remote sensing and portable devices have been expanding because: (a) no electric cables are required for their operation [ 2 ]; (b) they can be easily multiplexed; (c) their size can be reduced [ 3 ]; and (d) they are non-intrusive [ 2 ].…”

The implementation of signal filters in a real-time form requires a tradeoff between computation resources and the system performance. Therefore, taking advantage of low lag response and the reduced consumption of resources, in this article, the Recursive Least Square (RLS) algorithm is used to filter a signal acquired from a fiber-optics-based sensor. In particular, a Long-Period Fiber Grating (LPFG) sensor is used to measure the bending movement of a finger. After that, the Gaussian Mixture Model (GMM) technique allows us to classify the corresponding finger position along the motion range. For these measures to help in the development of an autonomous robotic hand, the proposed technique can be straightforwardly implemented on real time platforms such as Field Programmable Gate Array (FPGA) or Digital Signal Processors (DSP). Different angle measurements of the finger's motion are carried out by the prototype and a detailed analysis of the system performance is presented.

“…In the context of optical fibre sensors, they have been widely used and studied in many application areas to sense physical-related parameters such as strain, stress, pressure, vibration, current, rotation, displacement and bending. In addition, optical fibre sensors have also been employed for various kinds of chemical parameters such as liquid flow (Rehman et al, 2011), composition (Wolfbeis, 2006), and level (Ilev and Waynant, 1999b) as well as for gases detection, monitoring its presence and concentration (Manap et al, 2009;Mulrooney et al, 2007).…”
