报告摘要:
光的轨道角动量(OAM)包含一系列非受控的正交状态,可用来提高数据传输的信道容量。迄今为止,相关的工作集中在利用轨道角动量模式进行编码/解码以及多路传输以达到最大数据通道数和传输能力。本报告将介绍基于OAM的多点显示探索性研究工作。多视点图像信息在传递到不同视点方向之前采用OAM光束阵列进行编码。随后使用不同的OAM模式进行对二维信息进行编码和解码以获得三个视点的显示图像。任意OAM编码状态均可以有选择地进行恢复。OAM在未来的多视点显示系统中具有潜在应用价值。
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.  So 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 capacity. The viability of using OAM to create multiscopic 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.
