Principle of the self-measurement based on optical fibres; (a) optical camera, where the reflective prism is installed on the truss of the second mirror and the CMOS sensor and optical fibre are installed on the
The salinity sensors developed in this work are based on optical fibre sensing elements consisting of optical cavities within the fibres. The cavities act as FP interferometers rendering the presence of a certain refractive index, which is detectable by a phase change of the interferometric response ...
In principle, the Sezawa mode is a guided wave, in which the acoustic velocity of the top piezoelectric layer is lower than that of the substrate or sub-layer beneath. Thus, the wave can propagate through the interface or interlayers with a higher velocity than that of the top layer [45...
A Hinge site is a discrete location along a fibre link which is exposed to environmental perturbations usually where buried fibres lead to optical devices along the network system. The variation of PMD with wavelength at a fixed time in this study was stochastic. This is due to the presence ...
3 All optical local quantum network 3.1 Quantum information with continuous variables For quantum information based on optical systems, two different kinds of quantum variables are used, which are discrete variables and continuous variables, respectively. Discrete and continuous variables are quantum varia...
A demonstrator has been built in which a pipe valve can be opened and closed incrementally by direct optopneumatic control of the 3 to 15 lbf/in2 actuator. The optical energy is provided by inexpensive laser-diodes. The infrared fight is conveyed by optical fibres to miniature convertor cells...
Principle of the self-measurement based on optical fibres; (a) optical camera, where the reflective prism is installed on the truss of the second mirror and the CMOS sensor and optical fibre are installed on the focal plane; (b) optical fibre source, which is a two-lead p-n ...
In a method for spinning of opened fibres of linear textile structure, the fibres are conveyed by suction in an air stream into a spinning chamber which is formed between a conical rotor rotating at high speed and a stationary hollow cone. The air stream passes through the rotating cone in ...
Several optical interrogation points are located along the channel which allows to evaluate different device variations within a single fluidic channel. Finally, the sample exits the chip through the waste outlet. We define the coordinate axes as shown in Fig. 1a: in flow direction (X), in-...
The principle was validated on an etched diffraction grating, which successfully split the arbitrarily polarized light containing four wavelengths into eight channels with single-polarization and single-wavelength signals. Polarization-dependent losses of 0.5–1.8 dB, minimum insertion loss of 0.5 ...
