Project Details


The main goal of the project is the study and characterization of the modulation of the twisted nematic liquid crystal panels for the generation of diffractive elements and the use of panels in optical image processing. The amplitude and phase modulations, the changes of the light polarization state and their dependence with the wavelength will be studied. The main objective proposed in the project to be developed at the UAB is the application of the liquid crystal panels as amplitude and phase spatial light modulators and its use with polychromatic light. First, we will study the modulation characteristics and the appropriate combination of panels and other polarization devices needed to obtain the desired modulation. Next, we will explore different applications: diffractive lenses, apodizers to modify the optical system response, their use in interferometric set-ups to measure the phase, hyper spectral image capture and its processing. The main objective proposed in the project to be developed in the Universidad Miguel Hernández leads with the application of liquid crystal displays as spatial modulators of the polarization state of light. Different aspects are proposed like the application to generate diffractive planar structures based on the spatial change of the state of polarization , or to implement birefringent lenses. The study of multiple reflections in the liquid crystal display and its effect on its modulation response is also proposed, together with its application to design birrefringent tunble filters
