The artistic use of parallax and lenses revealing the invisible in holography
There are many artistic resources offered by holography: third-dimension
registration and reconstruction, immateriality, color interpretation, holographic space, realism,
etc. But there are a few of them which are very characteristic and singular of that media such as
the inversion of parallax, and the possibility of making invisible to turn into visible. Current
paper aims to discuss key issues concerning with the aesthetic use of those special features.
It is based on theoretical as well as critical analysis of the production by some of the most
outstanding holographic artists who have made use of such interesting resources
A Flexible Implementation of a Matrix Laurent Series-Based 16-Point Fast Fourier and Hartley Transforms
This paper describes a flexible architecture for implementing a new fast
computation of the discrete Fourier and Hartley transforms, which is based on a
matrix Laurent series. The device calculates the transforms based on a single
bit selection operator. The hardware structure and synthesis are presented,
which handled a 16-point fast transform in 65 nsec, with a Xilinx SPARTAN 3E
device.Comment: 4 pages, 4 figures. IEEE VI Southern Programmable Logic Conference
