Addressable spatial light modulators for eye-tracking autostereoscopic three-dimensional display using a scanning laser

A scanning laser-based back light three-dimensional (3D) display capable of rendering full-resolution, low crosstalk, and vivid 3D depth perception has been developed by incorporating time-sequential multiplexing and eye-tracking technologies. This system includes three main subsystems: a scanning l...
