Abstract: Orbital angular momentum (OAM) of light has an unbounded set of orthogonal states and can be used to enhance the channel capacity of data transmission. The viability of using OAM to create automultiscopic displays was explored. Multi-view image information is encoded using an OAM beam array before being sorted into different view directions. Subsequently the encoding and decoding of two-dimensional information using different OAM modes was investigated for a three-view display to show any OAM coded state can be recovered selectively. The experimental demonstrations suggest that OAM could potentially serve as an alternative platform for future multi-view display systems.
