The gyroscope system determines the rotation rate by measuring the net phase difference between the two beams, which is proportional to the rotation rate.Ī high performance fiber gyro system must be able to accurately detect phase differences due to rotation, while minimizing or being able to compensate for phase differences due to other sources, such as temperature effects. In an optical gyroscope, two counter-propagating optical beams are brought into interference in a Sagnac interferometer after travelling around a fiber-optic loop. Interested? Please contact our dedicated FOG-team: fog at nedaero dot com or call us at tel.Fiber optic gyroscopes (FOGs) have many important applications in navigation and positioning systems, angular velocity sensors, stabilization equipment, and recently, in autonomous vehicle guidance backup systems for GPS-inaccessible areas. Conventional mechanic gyroscopes will be replaced more and more by this reliable and maintenance-free Fiber Optic version.įiber optic technology without moving partsĪnalogue voltage output and Build-In-Test functionality dynamic range, bandwidth, bias-stability, noise and physical/environmental specifications.
The modular design enables tuning of specifications to customer specific applications, e.g. It has a high reliability and has a forceful, robust design. The FOG contains no moving parts and has obviously hardly any signs of wear. This system operates autonomous from a GPS system. This system is called an Inertial Navigation System (INS). Once you connect the IMU to a computer, you can determine the orientation, positioning and speed of the object. The unit can be used for attitude control and navigation of missiles, drones, etc. An IMU shows the acceleration and angular rate in three dimensions. Three FOG’s can be combined with three acceleration meters to end up as an Inertial Measurement Unit (IMU). Whenever FOGs are placed along the x-, y-, and z-axes, angular rates are measured in three dimensions. By measuring the phase-difference of two light beams, a Fiber Optic Gyro (FOG) calculates the speed in degrees per second with which it provides the turn rate of one rotational axis. The base consists of a spool on which an ultra-thin glass fiber is winded in two directions.
