Abstract

A new topology is introduced for an analog phase detector for open-loop fiber-optic gyroscopes which consists of a linearization function and a control function. It is shown that five different trigonometric functions are suitable to perform the linearization function. It is shown that by introducing a feedforward loop, an exact replica of the input phase will be produced at the detector output. In addition, a technique is also presented which increases the angular range of the phase detector significantly beyond the +/- 3 pi range which is the limitation of the trigonometric generators in the circuit.
