Paper Abstract

The light transmission factor of a device containing a liquid crystalline layer between crossed polarizers was estimated considering the losses by reflection at the separation surfaces and the phase change induced by the liquid crystalline layer for a monochromatic radiation. The computed transmission factor of this device and that experimentally obtained were compared in this study. The differences between the intensities in the computed and experimental spectra are explained by the diffusion phenomenon in liquid crystalline layer. The changes induced by an external electric field both in the values of the main refractive indices and in birefringence determine modification for the light transmission factor of the used device. The results obtained in this study could be applied to design polarization filters in the visible range.
