Study on Dead Zones of Fiber-Optic Gyros

摘要

This paper addresses the issue regarding dead zones in interferometric closed-loop fiber-optic gyros (FOGs). The causes of dead zones and their suppression methods are analyzed. Test methods for dead-zone detection and measurement are discussed. Dead-zone values are presented for FOGs produced by various companies-both Russian (Optolink, Perm Research and Production Instrument Company, and Elektropribor) and foreign (Honeywell and IXSEA).
