Abstract

High precision fiber coupled resolvers, which have a monotonically varying density analog track, or multiple binary tracks, have either stringent analog stability requirements, or require the interrogation of at least 10 optical channels. The resolver to be described has 3 variable modulus (6,10,15) analog tracks encoded using a weighted number system. The resolution exceeds that of a 10 bit binary resolver of comparable size with reduced optical complexity, and has moderate (3%) analog stability requirements. Degradation characteristics compare favorably with those of an analog sensor.
