Title: The Innovations of Yun Li
Introduction
Yun Li is a prominent inventor based in Ottawa, Canada. He has made significant contributions to the field of optical sensing technology. His work focuses on developing advanced sensor systems that utilize innovative techniques to enhance performance and accuracy.
Latest Patents
Yun Li holds a patent for a "Distributed Brillouin sensor system based on DFB lasers using offset locking." This system features two distributed feedback (DFB) lasers that are locked at the Brillouin frequency of optical fiber through an offset locking method. The design includes a coupler that splits the laser output into two parts, which are then sent to two photodiodes. The outputs from these photodiodes are directed to a mixer, followed by a PID controller and a current controller. The lasers operate at a wavelength of 1550 nm, and the PID controller is responsible for locking the frequency difference. An optical delay line is incorporated to facilitate frequency tuning of the DFB lasers around the Brillouin frequency of the optical fibers. Additionally, a lock-in amplifier is utilized to maintain the DC level of the optical modulator at a minimum. This innovative approach has the potential to significantly improve the capabilities of distributed sensing systems.
