Abstract
A novel fiber optic gyroscope with low coherence laser as driving light source is designed in this letter, the low coherence laser has higher average wavelength stability and lower relative intensity noise which is achieved by using Gaussian white noise phase modulation to broaden the linewidth of a DFB laser. The scale factor stability of FOG can be effectively improved when applied to FOG research.
