Electromagnetic waves have linear momentum, orbital angular momentum, and spin angular momentum. The orbital angular momentum carried via vortex beams has considerable application potential in contemporary optical technology and has important application value in the fields of classical communication, quantum communication, optical manipulation, and rotation detection. Recently, domestic and foreign researchers proposed various techniques for detecting beam orbital angular momentum, including diffraction grating, interferometry, Doppler analysis, and metasurface methods. Compared with other methods, the metasurface method has the advantages of high efficiency and strong light manipulation. This paper primarily introduces several methods for measuring beam orbital angular momentum using metasurfaces, as well as their research progress and development status.
