摘要： We fabricate a stereoscopic hologram of an object by capturing a sequence of 2D images of the object, moving camera along a linear axis past the object and keeping the optical axis of the camera perpendicular at each of the positions. The camera lens and image recording surface are translated along the axis such that a fiducial part of the image does not move. The sequence is replayed and a first volume hologram is recorded by recording holograms of the captured images on a diffusing screen in different spatial locations on a surface of the first volume hologram. This is then replayed to form a stereoscopic image of the object and a second, volume reflection hologram of the replayed image is recorded to provide the stereoscopic hologram. A central image of the sequence is aligned to the fiducial part of the holographic image to make the resulting hologram “user-friendly”.

摘要翻译：我们通过拍摄对象的2D图像序列来制作物体的立体全息图，沿着线轴移动摄像机经过物体并保持摄像机的光轴垂直于每个位置。相机镜头和图像记录表面沿轴线平移，使得图像的基准部分不移动。重放序列，并且通过在第一体积全息图的表面上的不同空间位置的漫射屏幕上记录捕获的图像的全息图来记录第一体积全息图。然后将其重放以形成对象的立体图像，并且记录重放图像的第二体积反射全息图以提供立体全息图。序列的中心图像与全息图像的基准部分对准，以使得所得到的全息图“用户友好”。
