Abstract
This paper discusses yet another image operation performed in real time by the LCLV. Because of the birefringent properties of the liquid crystal used in its manufacture, a light intensity distribution imposed on the input plane of the liquid crystal maps as a reflectance function proportional to wavelength on the output plane. Using this 'spectral shift' of the light reflected from the output plane an optical device can be constructed which will cause dispersion proportional to input intensity gradients, which, in turn, enables the device to produce depth and shadowing effects in real time. A brief description of the operating characteristics of the LCLV will be discussed along with a method for using the 'spectral shift' distribution produced on the output plane of the device. Algorithms for producing stereo effects are reviewed followed by a description of the configuration of a system incorporating the LCLV to produce stereo effects. Finally, possible future uses for the device are suggested and further work proposed.
