Abstract
We propose novel depth-fused three-dimensional (DFD) method using polarization distribution, which is one kind of multifocal plane display that provides autostereoscopic image with small visual fatigue. The DFD method is based on the characteristic of human depth perception when the luminance-modulated two-dimensional (2D) images are overlapped. The perceived depth position is decided by the luminance ratio of each plane. The proposed system includes the polarization selective scattering films and the polarization modulating device. The polarization selective scattering film has the characteristics of partial scattering according to the polarization state and transmits the rest light from the scattering. When the films are stacked with the scattering axis rotated, each layer of film provides different scattering ratio according to the incident polarization. Consequently, the appropriate modulation of polarization can provide DFD image through the system. The depth map provides depth information of each pixel as a gray scale image. Thus, when a depth map is displayed on a polarization modulating device, it is converted into a polarization distributed depth map. The conventional twisted nematic liquid crystal display can be used as a polarization modulating device without complicated modification. We demonstrate the proposed system with simple experiment, and compare the characteristic of the system with simulated result.
