3D Imaging System using Multi-focus Plenoptic Camera and Tensor Display

In this paper, we introduce a 3D imaging system using a multi-focus plenoptic camera and a tensor display. A multi-focus plenoptic camera is a powerful device that can capture the light field (LF), which is interpreted as a set of dense multi-view images. This camera has the potential to acquire a LF having high spatial/view resolutions and deep depth-of-field. A tensor display, which consists of a few light attenuating layers stacked in front of a backlight, can visualize a light field with high resolution. To display the captured data by a multi-focus plenoptic camera, we need to extract multi-view images. For this, we propose a sophisticated rendering process for the complicated optical system of multi-focus plenoptic cameras. The multi-view images are converted to a multi-layer representation for the multi-layer display, i.e. tensor display. To demonstrate the effectiveness of this system, we conducted both computer simulations and experiments on our prototype display.
