Abstract

We experimentally demonstrate beam radial displacement and azimuthal rotation angle measurements using the intensity gradient of a beam composed of multiple OAM modes. Compared with a Gaussian beam or a beam carrying two opposite OAM modes, using a beam composed of multiple OAM modes can improve the measurement accuracy with the same beam power.
