摘要

We trained a neural network based on Resnet to improve the sensing accuracy in measuring the magnetic field applied on a Magneto-optic effect crystal, Bi4 Ge3O12 (BGO). The sensing system implements the superposition of vortex beams carrying orbital angular momentum (OAM) with topological charge of ±1. Such composited OAM beams passing through a linear polarizer wi...
