Abstract
We propose a mode recognition method based on sparse coding for beams carrying orbital angular momentum. Intensity profiles of Laguerre-Gaussian (LG) beam having different topological charges (TCs) are used for sparse dictionary learning and recognition process. High-accuracy recognition is achieved for LG beams with TCs from 0 to 6.
