摘要： Temperature is measured remotely by supplying a measuring pulse of a first wavelength via optical fibres to a sensor element formed of a material exhibiting temperature dependent absorption at this first wavelength. A reference pulse at a second wavelength is also directed through the sensor element, the second wavelength being selected to be transmitted through the sensor element substantially independently of temperature variation. A receiver determines the intensity of the measuring and reference pulses after transmission through the sensor element to generate signals V1 and V2 respectively. The receiver output V3 during a dwell period in the absence of either measuring or reference pulses is also measured. A value Z representing the sensor temperature is determined from Z = (V1 - V3)/(V2 - V3). Wavelength dependent errors are avoided by keeping the light source at a constant temperature. Optical feedback ensures the light source is driven to produce pulses of constant intensity.

摘要： A sensor assembly (1) comprises an optical fibre (4) and a transducer (23) arranged to apply transverse strain to a localised portion (24) of the fibre. Birefringence effects induced by the fibre strain are remotely sensed to obtain a signal representative of the transducer input which in turn is connected to a current sensing coil (34) thereby enabling electric current in a conductor (32) to be remotely sensed. The fibre is a metal coated fibre having a metallic jacket (19) enclosing a silica core and doped silica cladding layer. Damage to the fibre and the effects of creep are thereby avoided. The resulting sensor is particularly suited to the measurement of high currents in power distribution systems.

摘要： Light is transmitted from a local station (4) to a remote station (2) via an optical fibre (7) to supply a device (1) with light of constant polarisation state and intensity. The effects of external perturbation on the polarising state of transmitted light through fibre (7) are compensated by a mechanical transducer (18) acting on the fibre at the local station (4), a polarising beam splitter (11) being provided at the remote station and deflecting light through a second fibre (13) to a detector (14) at the local station. Fluctuation in intensity of light received via the second fibre (13) is used to generate a feedback signal acting on the transducer (18). The effects of external perturbations acting on the fibre (7) to produce variation in intensity of the transmitted light are similarly compensated by modulating the output of light source (3). A non-polarising beam splitter (30) at the remote station is used to sample the received intensity via a third fibre (32) and the intensity of the light source (3) is modulated accordingly by means of a detector (34) and feedback circuit (36). The method is useful in remote powering of fibre optic sensors over extended distances.
摘要翻译：光通过光纤（7）从本地站（4）发送到远程站（2），以向具有恒定偏振态和强度的光提供装置（1）。外部扰动对通过光纤（7）的透射光的偏振状态的影响由在本地站（4）上作用在光纤上的机械传感器（18）补偿，偏振分束器（11）设置在远端站和通过第二光纤（13）将光偏转到本地站处的检测器（14）。通过第二光纤（13）接收的光的强度的波动用于产生作用在换能器（18）上的反馈信号。通过调制光源（3）的输出，可以同样地补偿作用在光纤（7）上产生透射光强度变化的外部扰动的影响。远程站处的非偏振分束器（30）用于经由第三光纤（32）对接收的强度进行采样，并且通过检测器（34）相应地调制光源（3）的强度和反馈电路（36）。该方法在远距离提供光纤传感器方面非常有用。
