Copying Holograms

Applied Optics, 1966
A technique for producing many copies from one hologram is presented. This method involves using either the real or the virtual image (or both) reconstructed by a hologram as an object for a second hologram, with the undiffracted or zero-order wavefront being used as the reference beam.

Holograms for acoustics

Nature, 2016
Holographic techniques are fundamental to applications such as volumetric displays, high-density data storage and optical tweezers that require spatial control of intricate optical or acoustic fields within a three-dimensional volume. The basis of holography is spatial storage of the phase and/or amplitude profile of the desired wavefront in a manner ...

Augmenting Holograms

IEEE Computer Graphics and Applications, 2006
The goal of the HoloGraphics project at Bauhaus-University Weimar is to investigate possibilities of combining the advantages of conventional holograms - such as high visual quality and realism, support for all depth queues and for multiple observers at no computational cost, and space efficiency - with the advantages of today's computer graphics ...

Weigert hologram

Applied Optics, 1995
The Jones matrix is obtained for a film with a photoinduced anisotopy. The anisotropy of the film is considered to be caused by photoinduced anisotropic grains. On the basis of the Jones matrix we study Weigert's hologram of linearly polarized plane waves.
