Fiber-Optic Rotation Sensors. Tutorial Review
Allthe optical rotation sensors under development are based on the Sagnac effect which generates an optical path difference nL that is proportional to a rotation rate~.
Fiber optic sensor embedded in robotic systems for 3-D orientation
We integrated three rotational sensors on a single optical fiber to measure rotation of roll, pitch, and yaw and installed on robot manipulator where three scenarios are considered.
Fiber-Optic Sensors for Measurements of Torsion, Twist and Rotation:
In these configurations, conventional fiber-optic strain sensors (mostly FBGs) are applied to measure directly the shear stress at the surface of the measurement body, while this measured stress is then
Fiber Optic Sensors: Fundamentals, Principles & Applications
Radiation absorption excites an orbital electron to a higher energy level. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating
Fiber-optic vibration sensing—I: Rotation measurement
The fiber-optic rotational seismometer is based on the Sagnac effect and relies on mature fiber-optic gyroscope technology to measure the rotation components of vibration.
Fiber-Optic Sensors for Measurements of Torsion, Twist and Rotation:
This paper provides an overview of basic approaches and a review of current state-of-the-art in fiber optic sensors for measurements of torsion, twist and/or rotation.
Fiber Optic Gyroscopes
Fiber Optic Gyroscopes (FOGs) are high-precision sensors that measure angular velocity (rotation) using the principles of light interference in a fiber optic coil.
Rotation angle sensor based on magnetostrictive materials and fiber
In this work we propose and investigate a new concept for a rotational angle sensor based on magnetostrictive materials and FBG strain sensors.
Fiber Optic Sensor for Measuring Rotation
The two arms consist of optical fiber wounded in circular shape. Each laser beam propagates in opposite direction to the other. When the system was rotated, a time difference between these two laser
