FIBER OPTIC GYRO (FOG) High performance – Tough environments

Trackfire land

Contact

In guns, missiles, sights, cameras and antennas, stability is key. Saab’s Fiber Optic Gyros, FOG, are designed to provide maximum stabilisation in tough environments. They feature solid-state, low-drift, high shock usability, small size and short start-up time and are available as basic single axis FOG sensor, 1, 2 and 3-axis solutions with analogue or digital outputs.

Basic design

The Saab FOG sensor is a fiber optic ring interferometer comprising fiber coil, phase modulator, two fused fiber optic couplers, fiber optic polariser, super-luminescent light module and photo receiving module with pre-amplifier. The electronic part is a processing PCB that converts the optical module output into rate proportional voltages.

 

FOG adaptation to requirements

In addition to offering and selling standard configurations a typical procedure for Saab is to design complete rate gyro solutions by adapting our sensors and our modular electronics to customer requirements. The basic configuration data-sheets available as downloads are examples of standard configurations which could be modified to different customer requirements.
