New possibilities in the utilization of holographic screens
Jose J. Lunazzi
Directionality in a holographic screen may be useful for projecting images to be seen in complete horizontal parallax. The continuous sequence of views from an object may be transf…
Holophotography with a diffraction grating
J. J. Lunazzi
Color encoding of depth is shown to occur naturally in images of objects observed through diffraction gratings under common white light illumination. A synthetic image is then obta…
Olmec mirrors: an example of archaeological American mirrors
J. J. Lunazzi
Archaeological mirrors from the Olmec civilization are described according to bibliographic references and to personal observations and photographs.
On the quality of the Olmec mirrors and its utilization
J. J. Lunazzi
Archaeological mirrors from the Olmec civilization were analyzed in the context of bibliography produced in the last two decades. Photographs of its images are showed as a proof of…
Photographing by means of a diffractive axicon
J. J. Lunazzi, D. S. F. Magalhaes
In this paper we demonstrate that the light diffracted by a simple compact disc can be used to generate photographic images of a certain kind. Being the compact disc an axicon that…
Holoprojection of Images by a Double Diffraction Process
J. J. Lunazzi
Three dimensional images having continuous horizontal parallax were developed by wavelength enconding of view followed by a natural decoding process of projection onto a diffractiv…
