The topic of this research group meeting is "Optical System Cross-correlation", interpret the system structure of the paper in detail and the basic principle of using optical signals to achieve RF modulated wave auto-correlation and cross-correlation, and analyze the innovations of the system in depth.

Pang introduced the basic principle of the new iterative method, and carried out the simulation and measurement work. On the sensing length of 125 km, he measured the vibration of 20 Hz ~ 50 kHz and used the maximum strain of 200με, which proved the long detection range, wide response frequency band and large dynamic range of the system. He also demonstrated the potential of this approach for distributed vibration detection and location. Together with teachers and brothers, he sorted out his thoughts and made clear the next work plan.
