Study of light ray concentrated 3D display to dramatically improveimage qualities

三维显示的空间成像方案如电全息和积分成像被认为是最有前途的。然而，这些方案对显示设备的要求远高于目前的技术水平，需要在实际应用中取得突破。在本研究中，我们提出了从3D显示中射出有限数量光线的新技术，并通过使用透镜片和定向背光作为实际实现之一来确定该技术的原理。

The spatial imaging schemes of three dimensional display such as electro-holography and integral imaging are thought as the most promising. However these schemes require display device which has huge number of pixels far above current level of technologies, a breakthrough is necessary to be in practical use. In this study, we proposed new technique that limited number of rays are shot out from 3D display, and confirmed principles of the technique by using lenticular sheets and directional backlights as one of the practical implementations.
