Paper Abstract

In this paper we investigate the dependence of the bias in the interferometric fiber optic gyro versus the temperature gradient applied on the case of the sensor. Our main interest is in the coil winding pattern and in the design of the case. We describe here a method to calculate the influence of these two parameters on the temperature gradient performance. Our approach is to use a finite element model of the case and the coil. We describe then the winding pattern including the location and the length of each turn of the coil. With those data, we are able to compute the bias induced by the thermal transient effect.
