“…Common characteristics of the MIOC, such as insertion loss [3], the polarization extinction ratio [4], residual intensity modulation [5], etc., have been studied in detail. However, research on the MIOC response error is still preliminary, such as phase drift [6], center wavelength stability [7], etc.…”

The multifunction integrated optical chip (MIOC) is one of the most critical parts of the interferometric fiber optic gyroscope (IFOG), and research on the halfwave voltage of the MIOC is meaningful for a high-precision IFOG. In this paper, the correlation between the frequency and halfwave voltage, which affects the interference light intensity of IFOG, is presented theoretically. A widespread measurement method for frequency dependence of the halfwave voltage, based on lock-in amplification and sinusoidal modulation, is proposed. Further, the measurement result and the oscillation of interference light intensity in the Sagnac interferometer are presented, which are in great agreement with the theory. This paper proposes the frequency dependence of the halfwave voltage and provides a new error research direction for the improvement of the MIOC in a high-precision IFOG.

“…Optical coherence domain polarimetry (OCDP) based on white light interferometry is a distributed high-precision polarization-coupling measurement technology [1,2]. It has been widely used for distributed measurement such as the testing of long distance polarization maintaining fibre (PMF) devices [3] and the polarization crosstalk in fields of fiber optic gyro (FOG) [4]. For the OCDP used for evaluating the precision-grade FOG (performance range of 0.001°/h bias stability), the dynamic range and measurement sensitivity of the OCDP should be as high as 80 dB and − 10 8 rad, respectively [5,6].…”

We propose an optical delay line based on differential structure for improving measurement accuracy and extending scanning length of optical coherence domain polarimetry (OCDP). The differential delay line is composed of two independent graded refractive index lenses (GRIN) and a double-faced mirror. The OCDP measurement model with loss coefficient and measurement error caused by the GRIN-lens-based delay line is discussed. Compared to the general optical delay line based on a single GRIN lens, the fluctuation of the loss coefﬁcient of differential delay line is reduced to ± 0.1 dB with scanning range of 0.8 m, which corresponds to 80% improvement.
