Abstract

The Jet Propulsion Laboratory is developing a Fiber Optic Rotation Sensor (FORS) for use on the Mariner Mark II series of planetary explorer craft and in other space applications. FORS is a closed-loop, phase-nulling device and embodies a number of interesting innovations. Chief among these are the incorporation of the device's couplers, phase modulators and polarizer on a single lithium niobate (LiNbO₃) integrate optics chip and a novel means of reading out angular position and rotation rate based on optical beat detection Various aspects of the FORS design and operation are described and discussed. Particular attention is paid to analyzing errors attributable to polarizer imperfection and the so-called residual Michelson effect.
