In this paper we review the current state of development of fibre optic sensors, including those based on both monomode and multimode technology. For monomode techniques, a general formalism describing their optical characteristics is developed; electronic processing techniques and noise performance are also considered. Examples of their application in the measurement of temperature, pressure, strain, flow, rotation and magnetic field are described. Extrinsic devices such as velocimeters and vibrometers, and applications in holography, are also discussed. Multimode techniques based on intensity and wavelength modulation and quantum effects are considered, and their application to a wide range of measurands is reviewed. 相似文献

A new method of preparing fibre reinforced glasses is put forward, which is based on further developments of the known slurry
method and the sol-gel technique. This method combines the advantages of the two procedures. The prepregs are hot-pressed
and the influence of preparation parameters on the bending strength are investigated. The pressure, temperature, time of pressing,
granulation of the glass powder, the type of sol-gel solution and the gas atmosphere during the hot-pressing were all studied. 相似文献

Abstract We report on the construction and characterization of a novel fibre Raman oscillator which used fibre grating reflectors rather than discrete mirrors to form the Raman resonator. This was synchronously pumped by a c.w. mode-locked Nd : YAG laser operating at 1·06 µm. Spectral and temporal characteristics of such oscillators formed by two gratings and by one grating and a conventional mirror are presented. 相似文献

Abstract A fused fibre coupler has been used as a spectral filter in a femtosecond fibre soliton laser to eliminate the spectral sideband structure associated with periodic amplification of solitons in the regime where the characteristic soliton period of the generated pulses approaches that of the overall fibre laser loop length. 相似文献

Abstract: Fibre Bragg grating sensors have been developed as a strain measurement technique. With regard to practical applications, there is growing knowledge and experience. However, many application issues remain unsolved. These issues include signal interpretation, confidence in measurement accuracy, calibration, and zero-strain definition. This paper reports some issues which have been encountered in practical measurements and application trials. The investigation covers various aspects of strain measurement. The measurement accuracy in a composite laminate is found to be influenced by the formation of cracks in adjoined layers, interface between fibre sensor and host materials and nonuniform stress fields. 相似文献

AbstractPiezoelectric materials are capable of actuation and sensing and have found uses in applications including ultrasonic transducers, hydrophones, micropositioning devices, accelerometers, and structural actuators. A composite configuration for structural actuation having significant advantages over conventional piezoelectric actuators has been conceived, and the recent development of piezoelectric ceramic fibres < 100 μ m in diameter has enabled this concept to be realised. It is envisaged that these composites will find uses in contour control, non-destructive testing, vibration suppression, and noise control. The possibility of computer control using closed loop systems has led to these composites emerging as potential 'smart' materials and structures. Since their conception, less than a decade ago, significant advances have been made in many areas concerned with composite performance, such as fibre and matrix technology and configuration optimisation. These advances are charted, the fibre, matrix, and electrode technologies are reviewed, and the manufacture, modelling, and applications of these new piezoelectric composites, known as active fibre composites, are discussed. 相似文献
