In recent years, the optical storage and optical information processing technologies based on holographic and photonic techniques are suffering a huge improvement. On the other hand, Spatial Light Modulators (SLMs) based on LCoS microdisplays (PA-LCoS) open new possibilities to modulate the wavefront of a light beam. PA-LCoS are high resolution reflective devices which make possible the generation...
Parallel aligned liquid crystal on silicon (PA-LCoS) devices are widely used in many optics and photonics applications to control the amplitude, phase and/or state of polarization (SOP) of light beams. We present a novel model enabling to calculate the voltage dependent retardance provided by PA-LCoS devices for a very wide range of incidence angles and any wavelength in the visible. To our knowledge...
In this study the diffraction efficiency of diffuse-object holograms is compared with that of holographic gratings for a constant beam ratio and different intensities in order to analyzed the storage and reconstruction process with the same wavelength. When we work with the same wavelength in the register and reconstruction process, the refraction index modulation decreases. The material used is a...
