abstract

Polarization data of a SM gyroscope coil may correlate to drift that provides a method to statically predict a performance range of a coil during manufacturing or at a minimum before integration into a FOG assembly. The Crossover Free (CF) coils described here are thermally symmetric and lack fiber crossovers. This design allows possible expansion of depolarized FOGs beyond the research environment. To that end a series of double sided CF gyroscope coils were manufactured and analyzed using a 4 channel fiber coupled polarimeter. In addition the coils were tested on a single axis rate table in a FOG testbed. A polarimeter was used to measure the output polarization state of the stand-alone coils and when integrated into an experimental FOG testbed. In addition Shupe data of the CF coils was taken to determine the thermal sensitivity of the coils. Coil geometry and construction, polarimetric and traditional drift data, and Shupe performance will be presented.
