A novel autostereoscopic display system with the characteristics of variable viewing distance control,
real-time 2D/3D switchable display, and adjustable lens pitch using an acousto-optic lens (AOL) is proposed.
With the unique property of an AOL array, the proposed system can provide viewers to select
suitable viewing distances by adjusting the acoustic signal that is applied to the AOL array. With the
same property, the system can also be adjusted with an appropriate interpupillary distance (IPD) for personal
entertainment applications. The proposed system with adjustable lens pitch, can adopt to different
display panels with various resolutions and/or composited images. The operation principle of the system
is analyzed with a set of design parameters and a set of simulation results to facilitate the implementation
of the system and to verify the validity of the approach.
