| Sumario: | A wide range of applications in diffractive optics (DO) have benefited from the use of liquid crystal (LC) panels, ranging from imaging applications, both in mono and in polychromatic illumination, in optical signal processing or in digital holography to name a few. These are fields where we have dedicated a large research effort in recent years and here we will describe part of our results. We have studied the design and implementation of apodizing filters in imaging systems, which can be e.g. applied to compensate the longitudinal secondary axial color (LSAC). We have also analyzed the design of diffractive lenses by the generation of phase elements resulting from the multiplexing of diffractive lenses to control de polychromatic point-spread function (PSF). We analyze the use of transmission liquid crystal displays and liquid crystal on silicon (LCoS) displays that work in reflection. The later tend to exhibit temporal fluctuations in the phase modulation, which we have analyzed in order to produce more efficient diffractive optical elements (DOEs). © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE). |
