Single-mode optical fiber interferometers used with measurement or sensing systems should be stabilised to achieve high measurement accuracy and linearity in the presence of differential phase drift in their arms resulting from temperature fluctuations and other types of environmental disturbances.
We propose a no¨el pulsed fiber laser rotation sensor with a LiNbO integrated optic circuit, Sagnac fiber loop, Er-doped fiber, and 3 semiconductor pumping lasers. A simple analysis is completed and the output equation is deri¨ed. The ¨ariance of the output pulse when rotation occurs is also analyze
