Instrument applications of large-core optical fiber cable transfer(LOCAT) theory,

摘要

Abstract: The transfer function theory for large core optical fiber (bare fiber) and fiber cable (LOCAT) reveals a ray's actual interaction with the fiber lightguide. By applying this new tool in a fiber optic instrument design, we have improved the repeatability and stability of this fiber optic temperature instrument from 4$DGR@C to 0.2$DGR@C at 1000$DGR@C. Several new concepts such as cable bend increments, fiber status, and fiber status stability also are discussed in this paper. !6
