Abstract

An optical fiber gyroscope configuration which utilizes dual wavelength determination of the Sagnac shift is described. It is shown that this provides a means of extending the unambiguous rotation sensing range, and thus the dynamic range, of the gyroscope. An increase in unambiguous sensing range ~ x 45 is demonstrated using an all-fiber gyroscope, giving an absolute dynamic range of ~ 10 ⁶.
