Numerical Analysis and Recursive Compensation of Position Deviation for a Sub-Millimeter Resolution OFDR
We analyze the source of the position deviation and propose a demodulation recursive compensation algorithm to ensure a sub-millimeter resolution in improved optical frequency domain reflectometry. The position deviation between the geometric path and optical path changes with the temperature or str...
