Embodiment Construction
[0047] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0048] At present, the use of OFDR technology for static measurement has been relatively mature, but for the measurement of high-frequency disturbance signals, there is no relatively complete system for measurement. Based on this problem, this example provides a high-performance distributed optical fiber sensing system based on Ahtz ultrafast pulse scanning, which can realize the demodulation of...
