Optical fiber sensors present several advantages in relation to other types of sensors. These advantages are essentially related to the optical fiber properties, i.e., small, lightweight,
A rotation sensor refers to a device that detects and measures the rotation of a component or object. It can be used to determine the direction and number of rotations, providing valuable information for
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.
The measurement of rotation is of considerable interest in a number of areas. For example, inertial navigation systems as used in aircraft and spacecraft depend critically on accurate inertial rotation
The fiber optic gyroscope (FOG) is based on the Sagnac effect – Light beams propagating in opposite directions in a rotating frame experience a different optical path length
A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals
A three-dimensional (3-D) rotation sensor, also known as an orientation sensor, measures the orientation or attitude of an object in 3-D space . These sensors are often used in robotics to
A highly precise rotation sensor may be used to measure any changes in the length of the day and to detect torsional oscillations in the earth caused by earthquakes.
Our sensing platform is based on Fiber Bragg Grating (FBG) technology and can improve efficiency, enhance performance, productivity, and safety for rotating equipment.
