Recent advances in optical technology have enabled the encoding of information onto light beams, such as orbital angular momentum (OAM). OAM is a quantum number that describes the angular momentum of an object in space, such as a photon. Now, researchers have demonstrated that OAM-encoded diffractive networks can be used to classify objects with high accuracy.

In a new study, researchers from the National Institute of Information and Communications Technology (NICT) in Japan used OAM-encoded diffractive networks to classify objects with significantly higher accuracy than traditional deep neural networks. The results of the study suggest that OAM-encoded diffractive networks may be a promising approach for advanced classification tasks, such as medical diagnosis and surveillance.
