ASE FIBER OPTIC

The principle of fiber optic gyroscope is called Sagnac effect in physics. In a closed optical path, two beams of light from the same source, propagating relative to each other, converging to the same detection point will produce interference, if the closed optical path exists relative to the rotation of inertial space, the beam propagating along the positive and negative directions will produce a difference in optical range, the difference is proportional to the angular velocity of the upper rotation. Using the photodetector to measure the phase difference to calculate the angular velocity of the meter rotation.

As the transmitting device of fiber optic gyroscope, its performance has a great influence on the measurement accuracy of fiber optic gyroscope. At present, 1550nm wavelength ASE light source is commonly used in high precision fiber optic gyroscope. Compared with the commonly used flat spectrum light source, ASE light source has better symmetry, so its spectral stability is less affected by the ambient temperature change and pump power fluctuation; meanwhile, its lower self-coherence and shorter coherence length can effectively reduce the phase error of fiber optic gyroscope, so it is more suitable for application in Therefore, it is more suitable for high precision fiber optic gyro.
