"Microwave Photonic Sensing for High Performance Displacement Measureme" by Bairun Nie, Yuxi Ruan et al.
Microwave photonic (MWP) sensing and measurement are envisioned to be a promising alternate to the conventional pure electronic or optical solutions. By using a semiconductor laser (SL) subjected to external optical feedback (EOF) operating at period-one (P1) dynamic state to generate MWP signals, a high performance sensing system is proposed for displacement with wide measurement range and super-high resolution. Through analysis on the state diagram of the system and its dynamics in P1, the rel...
