“…With the advantages of short response time and programmable gray level distribution, SLMs have been used widely in many research areas [21][22][23], such as image processing, digital holography, computer generated holograms, data encryption, and beam shaping. As a key element in the holographic encoding system, the SLM is applied to modulate the object beam and the reference beam.…”

We propose a novel configuration for angular multiplexing holographic encoding in which the signal beam and the reference beam are combined into a single beam. By using a spatial light modulator based on twisted nematic liquid crystals, the signal and the reference beams are modulated in amplitude mode and phase mode, respectively. The multiplexed interference patterns with the reference beams of different incident angles are recorded near the Fourier transform plane, and then the signals are selectively reconstructed by the corresponding reference beam. Both the simulation and the experiment of singlebeam angular multiplexed holography are performed with consistent results. Compared with the traditional angular multiplexing holographic recording system, the single-beam configuration is more compact, easier to adjust, and less sensitive to the vibration of the environment. Therefore, it will be more attractive for potential applications in many fields, such as high-density signal recording and data encryption.

“…In this work we apply a microscopic LC birefringence chromatic dispersion model for accurately predict the spectrum of the light transmitted by a TNLCD in the complete visible range for different polarization configurations. We show that it is possible to achieve a relatively large gamut by selecting an appropriate orientation of the polarizers in a TNLCDs cell [6].…”

We present the application of a simple physical model to accurately predict the broadband spectral transmittance and colorimetric properties of a twisted-nematic liquid crystal display (TNLCD). We spectroscopically calibrate the retardance parameters to evaluate the spectrum of the light transmitted by a TNLCD sandwiched between two linear polarizers. When the TNLCD is illuminated with a broadband light source, the full spectrum can be predicted as a function of the addressed grey level for any arbitrary orientation of the polarizers. Experimental results confirming the validity of the proposed systems are presented, both on the measured spectral responses as well as on the trajectories at different chromatic diagrams. The presented results can be useful for optoelectronic systems requiring an accurate control of the spectral characteristics of the light.

Abstract. In this paper, basing on the anisotropic properties of longitudinal inhomogeneous nondepolarizing media with linear phase anisotropy, more general type of media with elliptical phase anisotropy was studied. The features of propagation of light with privileged states of polarization were observed. Transformation of polarization states of eigenwaves along z axes of light propagation was studied. The orthogonalization properties inherent to this type of medium were obtained. Evolution of linear polarized light in this media was presented and discussed.
