Abstract
Nonreciprocal phase errors have been identified in Sagnac fiber-optic sensors which use acousto-optic modulators for frequency shifting. These errors have been observed in a system which uses the acousto-optic modulator as both a frequency shifter and the central beamsplitter which generates the counterpropagating light beams in the Sagnac interferometer. The amount of phase error generated is dependent on the acousto-optic modulator drive power as well as other acousto-optic parameters. Data is presented from an inter-ferometer which uses the acousto-optic modulator as a beamsplitter. The data shows good correlation with the predicted phase errors.
