Paper Abstract

This paper discusses some potential sources of scale factor error in an interferometric dynamically biased FOG. Scale factor formulae are derived for a serrodyne approach utilizing direct slope measurement, and an open loop direct phase reading (DPR) approach. The source wavelength, phase modulator characteristics and optical fiber parameters are addressed as sources of scale factor error for both moderate and tactical grade FOG applications. A look at the dependence of the predominant error sources on temperature, and how this dependence will affect the magnitude of the scale factor error, will be given. Methods of reducing or compensating for the errors are discussed. The resultant impact on FOG design is examined. Scale factor limitations are examined for each of the above approaches, and comparisons are made between the two methods.
