摘 要：Te orthogonal nature of diferent orbital angular momentum modes enables information transmission in optical communications with increased bandwidth through mode division *** far the related works have been focused on using orbital angular momentum modes to encode/decode and multiplex point-based on-axis signals for maximum data channel numbers and *** orbital angular momentum modes can be utilized to encode/decode of-axis signals for multiplexing in twodimensional space is of signifcant importance both fundamentally and practically for its enormous potential in increasing the channel information *** this work,a direct use of orbital angular momentum modes to encode/decode and multiplex twodimensional images is realized in a scalable multiview display architecture,which can be utilized for viewing three-dimensional images from diferent *** efect of of-axis encoding/decoding and the resultant crosstalk between multiplexed diferent twodimensional views are *** on which,a color display of good image quality with four independent views is *** resolution of the decoded images is analyzed and the limitation of this approach ***,a spatially multiplexed data communication scheme is also proposed with such a two-dimensional encoding/decoding approach to signifcantly enhance the data transmission capacity in free space for future data communication needs.
