Topological Charge Identification of Superimposed Orbital Angular Momentum Beams Using Image Processing and ResNet

Not Accessible

Your library or personal account may give you access

Abstract

Image filtering, segmentation and ResNet are used to identify the topological charge (TC) of superimposed orbital angular momentum beams. 100% TC identification accuracy for ±1 to ±40 superimposed beams under different beam intensity is achieved.
