Abstract
A vibration response theoretical model is built to derive conclusion to show that the error rate amplitude of fiber-optic coil is proportional to amplitude and frequency of a sinusoidal acceleration
which is experimentally verified.A series of parameters are introduced to establish a comprehensive and quantitative evaluation system for vibration performance of a coil.A practical test system is set up to test the fiber-optic coils.The vibratin sensitivity is about 1°/(h·Hz)
with degree of nonlinearity error of about 10% and repeatability error of about 2 %.Bias drift induced by vibration is about 1°/ h
and different coils with different adhesives are tested to verify that the evaluation system can reflect the vibration performance of fiber-optic coil effectively and comprehensively.
