IXSEA - FOG
FIBER OPTIC GYROSCOPE
Fiber Optic Gyroscope (FOG) is an elegant application of a fascinating phenomenon, the Sagnac Effect. It uses optical waves propagating in a fiber optic coil to measure a rotation rate accurately.
Its design, which seems very simple, takes full advantage of the Reciprocity Principle on the propagation of light.
This fundamental principle allows a perfect device to be created from imperfect components!
At iXSea, our FOGs are the result of more than 15 years research and engineering, and can address the most demanding applications and performance - from 0.1°/h up to 0.001°/h.

technology for high performance applications over competing technologies. In particular, we show the advantages of the FOG technology over the Ring-Laser Gyroscope (RLG) technology.
In the first section, we emphasize the differences and similarities between FOG and RLG.
In the second section, we list several advantages of FOG technology.
ULTIMATE-PERFORMANCE FIBER-OPTIC GYROSCOPE: A REALITY
Author: Hervé C. Lefèvre.
The fiber-optic gyroscope started to be investigated in the mid-70s with the advent of optical-fiber communications. Today, it reaches ultimate theoretical performance and surpasses it well-established competitor, the ring laser gyroscope.
