Abstract: Embodiments described herein provide for a method of modulating an input light beam of an interferometric fiber optic gyroscope (IFOG). The method includes intermittently jumping a phase step to suppress dead band. During a first cycle, a first cycle raw rate is stored and a feedback signal is generated based on a jumped phase step. During a second cycle, a second cycle raw rate is stored and a feedback signal is generated based on the jumped phase step. During a third cycle, a third cycle phase step is generated by accumulating the first cycle raw rate with a second cycle phase step, and a feedback signal is generated from the third cycle phase step. During a fourth cycle, a fourth cycle phase step is generated by accumulating the second cycle raw rate with the third cycle phase step, and a feedback signal is generated from the fourth cycle phase step.

Abstract: Embodiments described herein provide for a method of modulating an input light beam of an interferometric fiber optic gyroscope (IFOG). The method includes intermittently jumping a phase step to suppress dead band. If a bit flip was clocked into a digital to analog converter generating the feedback signal at the beginning of a cycle in which the jumped phase step is implemented, the method includes at least one of re-introducing a rate difference corresponding to the bit flip, altering the timing of the bit flip, or altering the timing of the generating a feedback signal based on the jumped phase step.

Abstract: Embodiments described herein provide a method of modulating an input light beam of a fiber optic coil of an IFOG. The method includes intermittently jumping the phase step of a feedback signal to suppress dead band. Jumping the phase step includes: creating a jumped phase step during a first cycle of the IFOG, the jumped phase step having a whole value configured to cause a phase jump in the feedback signal and a fractional value corresponding to the fractional value from a phase step of a cycle immediately preceding the first cycle. Jumping the phase step also includes generating the feedback signal from a sum of the bias modulation value and the jumped phase step.
