Large-scale color holographic display capable of steering view window

Abstract

We present optical fiber based large-scale color holographic three-dimensional display using a pupil tracking technique for wide viewing angle display applications. One of the limitations in implementing a large-scale holographic three-dimensional display is the restrictive space-bandwidth product of the spatial light modulator. In our proposed method, motor control system for steering optical fibers as a light guide and pupil tracking system are used to overcome the limitation of space-bandwidth product by steering the view window according to a position of the pupil of the observer. The proposed method employing the holographic stereogram in order to deliver two holographic patterns of different perspectives of a 3D scene to both eyes of the observer, which successfully provides both of the accommodation and binocular disparity.
