Abstract:	Fiber-optic rate sensors have developed from laboratory breadboards into prototype units. In this project, we demonstrate the maturity of the technology and assess the feasibility of manufacturing low-cost rate sensors. SAGEM and Honeywell have collaborated on this work to develop a low-cost twoaxis fiber-optic rate sensor that, in addiiion to meeting the performance specifications, would satisfy the even more important cost goal. Specifically, we targeted developing a two-axis rate sensor that could be reproduced for about $1000 in quantities of 5000 or more units. To meet this cost constraint, an all-fiber, reciprocal, depolarized IFOG design was selected. In the prototype, we used an inexpensive .83 micron light source and would the rotation-sensing coil using inexpensive, single-mode telecom fiber. Several prototypes were built and tested. Design specifics will be described and prototype test data will be presented.
