Recent advancements in metrology are being driven by the innovative use of twisted light, which carries orbital angular momentum (OAM), allowing for ultra-high precision measurements. A research team led by Prof. Lixin Guo from Xidian University, in collaboration with experts from South Africa, published a comprehensive review in “Light Science & Applications” examining the evolution and future potential of optical metrology utilizing OAM. The paper discusses how incorporating OAM enables more comprehensive motion tracking and real-time analysis of complex media, significantly enhancing traditional measurement tools and introducing novel instruments. The researchers also highlight the emerging field of quantum metrology with OAM, indicating numerous opportunities for improved accuracy and efficiency. As the review spans applications from nano-sensing to cosmic measurements, it serves as a vital resource for both novice and experienced researchers in the field.
