Abstract

The paper defines current importance of scientific and technical problem of metrological characteristics improvement and functionalities expansion of optical fiber structure (OFS) monitoring systems on the base of two frequency probing. Analysis and synthesis problems which should be solved by development of the theory and technical equipment of optical reflectometers for OFS monitoring in two frequency domain (OTFDR) are considered. Questions of OTFDR application efficiency for OFS monitoring on the examples of OTDR with two frequencies filling of probing pulse, non coherent OTFDR with LFM modulated components, and two frequencies heterodyne for SCF-OFDR are examined.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
