Fibre Optic System for Monitoring Rotational Seismic Phenomena
We outline the development and the application in a field test of the Autonomous Fibre-Optic Rotational Seismograph (AFORS), which utilizes the Sagnac effect for a direct measurement of the seismic-origin rotations of the ground. The main advantage of AFORS is its complete insensitivity to linear motions, as well as a direct measurement of rotational components emitted during seismic events. Th...
متن کاملFiber gyro with squeezed radiation
Received December 11, 1990; revised manuscript received April 30, 1991 A pulse-excited Sagnac fiber interferometer can perform squeezing. If this squeezed radiation is injected into a second Sagnac interferometer that is functioning as a fiber gyro that is itself nonlinear, additional unfavorable squeezing occurs in the gyro. By proper phase adjustment of the injected squeezed radiation it is p...
متن کاملDetection of Excited Vibration Signals on the Latticed Fence Structure Using a Distributed Fiber Optic Sensor with Sagnac Interferometer
To detect external vibration signals on the latticed fence structure, distributed fiber optic sensor using Sagnac interferometer was fabricated and tested. Because of easy construction Sagnac interferometer was selected rather than MachZehnder type. The latticed structure fabricated with dimension of 180cm in width and 180cm in height, the optical fiber, 50m in length, distributed and fixed on ...
متن کاملSingle Mode Fiber Optic Sagnac Interferometer with Wireless Data Collection
Since the introduction of fiber optic gyroscope in the late 1970’s 1, the need for accurate inertial navigational instruments has driven the evolution of the device into complex open or closed loop designs manufactured with expensive polarization maintaining fibers and fused fiber optic elements. Our goal herein is to describe a novel fiber optic Sagnac interferometer design made with readily a...
متن کاملMulti-Stress Monitoring System with Fiber-Optic Mandrels and Fiber Bragg Grating Sensors in a Sagnac Loop
Fiber Bragg grating sensors are placed in a fiber-optic Sagnac loop to combine the grating temperature sensors and the fiber-optic mandrel acoustic emission sensors in single optical circuit. A wavelength-scanning fiber-optic laser is used as a common light source for both sensors. A fiber-optic attenuator is placed at a specific position in the Sagnac loop in order to separate buried Bragg wav...
