ABSTRACT
The orbital angular momentum (OAM) holography has been identified as a vital approach for achieving ultrahigh-capacity in 3D displays, digital holographic microscopy, data storage and so on. However, depth has not been widely applied as a multiplexing dimension in the OAM holography mainly because of the serious coherence crosstalk between different image layers. The multi-layered depth multiplexing OAM holography is proposed and investigated. To suppress the coherence crosstalk between different image channels, random phases are used for encoding different image layers separately. An image can be reconstructed with high quality at a specific depth from an appropriate OAM mode. It is demonstrated that the depth multiplexing of up to 5 layers can be achieved. This work can increase the information capacity and enhance the application of the OAM holography.
