T parameter is converted into L parameter.It, can be by timing node t to the distance of distributed fiberoptic sensor according to optical time domain reflection principle
Parameter L is calculated.
Specifically, calculation formula isWherein, L is position caused by t timing node modulated optical signal value
To the distance of optical signal transceiver equipment, c is the light velocity in vacuum, and t is timing node, and IOR is the folding of distributed fiberoptic sensor
Penetrate rate.
In the above manner, optical signal transceiver equipment obtains the second feedback signal f2(L, s), the signal include along distribution
