SANDOVAL-ROMERO, G.E.  e  NIKOLAEV, V.A.. Límite de detección de un giroscopio de fibra óptica usando una fuente de radiación superluminiscente. Rev. mex. fis. [online]. 2003, vol.49, n.2, pp.155-165. ISSN 0035-001X.

The main objective of this work is to establish the dependence of characteristics of the fiber optics gyroscope (FOG) with respect to the parameters of the superluminiscent emission source based on doped optical fiber with rare earth elements (Superluminiscent Fiber Source, SFS), argument the pumping rate election of the SFS to obtain characteristics limits of the FOG sensibility. By using this type of emission source in the FOG is recommend to use the rate when the direction of the pumping signal coincide with the superluminiscent signal. The most results are the proposition and argumentation of the SFS election as emission source to be use in the FOG of the phase type. Such a decision allow to increase the characteristics of the FOG sensibility in comparison with the use of luminiscent source of semiconductors emission which are extensively used in the present time. The use of emission source of the SFS type allow to come closer to the threshold of the obtained sensibility limit (detection limit) which is determined with the shot noise.
