Abstract

The relative phase shift of light transmitted through a liquid crystal television (LCTV) panel as a function of the applied voltage on the LCTV can be obtained by writing a Ronchi grating pattern to the LCTV and measuring the intensities in the diffraction pattern at the Fourier plane combined with the amplitude modulation factor. A kinoform is synthesized on the LCTV based on the measured phase shift demonstrating the phase-mostly modulation.
