WANG Gui-fu, HE An-zhi, LI Zhen-hua, et al. SLD effect on the performance of fiber optic gyro[J]. 2006, (6): 28-30+33. DOI: 10.13873/j.1000-97872006.06.009.
Characteristics of superradiance light emitting diode(SLD) are introduced and the effects on the performance of a fiber optic gyro(FOG) such as output power
central wavelength
full width at half maximum(FWHM)
degree of polarization(DOP)
input current of the SLD are analyzed from the point of view of theory and application
methods to solve these problems are given also.Experiments results shows that the output power control of the SLD is dominating to a low-medium accuracy fiber optic gyro.For high accuracy FOGs
the wavelength have to be controlled besides the output power should be controlled
