SYSTEM AND METHOD TO COMPENSATE FOR ARBITRARY OPTICAL FIBER LEAD-INS IN AN OPTICAL FREQUENCY DOMAIN REFLECTOMETRY SYSTEM |
摘要 |
A method for estimating a parameter includes: generating an optical signal, the optical signal modulated via a modulation signal having a variable modulation frequency over a period of time; transmitting the modulated optical signal from a light source into an optical fiber, the optical fiber including at least one sensing location configured to reflect light; receiving a reflected signal including light reflected from the at least one sensing location; and demodulating the reflected signal with a reference signal, the reference signal including a time delay relative to the modulation signal based on a distance between the light source and the at least one sensing location. |
