Speaker:  Prof. Jiang Junfeng (Tianjin University)

Inviter: Prof. Qu Junle

Time: April 6, 2023, 10:00-10:40 AM

Venue: Room 1206, the Zhiyuan Building, Shenzhen University

Abstract:

Rapid development of life science and medicine asks for continuous research and creation of new sensing technologies. In the 1^st part of the seminar, I will talk about Optical Fiber Sensors associated with echo wall resonance in the micro-cavity, including high-sensitivity temperature sensors, biosensors based on liquid crystal enhancement, laser enhancement, and microwave photon demodulation. In the 2^nd part, I will talk about Optical Fiber Sensors together with OCT to monitor the cardiovascular system, including all-fiber guided OCT system, vascular imaging and processing, three-dimensional reconstruction of the coronary by fusion of IVOCT and DSA, polarization-sensitive Catheter OCT system and its mathematical solution. Finally, I will talk about Optical Fiber Sensors associated with CARS, including wavelength modulation based on polarization vector adjustment and double solitons, time-frequency mixed wavelength modulation based on SSFS and chirped pulse delay, optic fiber probe excitation, etc.
