Abstract

A one-axis, fiber optic interferometer gyro has been constructed and tested. The device, based on a 670 meter length of single-mode optical fiber, uses a GaAlAs laser as a source, and phase sensitive synchronous detection to measure fringe shifts as a function of rotation rate. Using a calibrated rate table, rotation rates from 0 to 110 deg/sec have been measured. The device easily measures rates as low as 0.05 deg/sec with a signal-to-noise ratio of ten. Error sources and potential improvements will be discussed.
