In order to realize useful visual media such as 3-D images, we need effective technology for representing and utilizing dense light fields, that is to say, information of rays flying in the space. At first, this research formulates essential relation between some images structured appropriately and the light filed in the frequency domain. Then, a novel method for such image acquisition is proposed. Finally, based on the relation above, fast and robust reconstruction of a dense light field from the acquired images is achieved.

为了实现有用的视觉媒体，如三维图像，我们需要有效的技术来表示和利用密集的光场，也就是说，光线在空间飞行的信息。本研究首先在频域中建立适当结构的影像与光场之间的本质关系。然后，提出了一种新的方法，这样的图像采集。最后，基于上述关系，实现了从所获取的图像快速且鲁棒地重建密集光场。
