微波光子传感技术研究进展综述

Microwave photonics is a multidisciplinary field that studies the interaction between microwave and optical waves for the generation, transmission, processing, and measurement of wideband microwave signals by means of photonics. Microwave photonic sensors are one of the active sub-fields that uses optical sensors to probe the information of temperature, strain, pressure, etc. and microwave photonic techniques to extract the sensing information accurately, providing unique advantages of high resolution and high speed. This paper comprehensively reviews the recent progress in microwave photonic sensors, introduces the basic principle of microwave photonic sensing, and discusses the potential research directions in the future.
