Abstract

Research presented in this research is focused on developing and implementing novel photonic systems for instantaneous microwave frequency and displacement measurement, emphasizing cost-effectiveness, scalability, and high resolution. The research is encapsulated in three core studies: the design of all-fiber ultrafast ranging Lidar for medical motion management, the application of dispersive interferometry using picosecond laser pulses for laser ranging, and the integration of microwave photonic systems with digital signal processing (DSP) for enhanced measurement precision.

The work achieves micrometer-scale displacement accuracy and microwave frequency resolutions within ±1 MHz across wide dynamic ranges by leveraging dispersive interferometry and time-stretch techniques. The studies underline the advantages of picosecond lasers as an alternative to femtosecond systems, providing practical solutions to mitigate challenges in cost, complexity, and environmental stability.

Key contributions include the development of dual Mach-Zehnder interferometers for bidirectional displacement detection and the integration of advanced DSP algorithms to optimise frequency extraction under noisy conditions. The innovations demonstrate applicability in diverse fields, including biomedical applications such as patient motion monitoring during procedures where conventional techniques are limited and real-time monitoring with high precision is required. The techniques improve microwave frequency detection and precision metrology.
