Abstract
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”.
