“…The lens-less image forming by phase modulation of light with a spatial light modulator (SLM) theoretically gives 100% efficiency and allows any size of the final image, without any aberrations, noise and with real-time refresh on very large screens. Obviously, the main aspect that differ the theory from the experimental results is the hardware constraints and limitations of the SLMs currently available on the market [3]. To name a few of those aspects: the limited time response of the liquid crystal, the pixelated structure of the SLM, the non-100% fill factor, limited pixel count, lack of optical flatness, etc.…”

Dynamic electroholography is a suitable and promising technology of image display for future projection and near-eye displays. Until a new phase modulation technology is introduced, practical research assumes the use of pixelated spatial light modulators based on liquid crystals with electronically controlled birefringence leading to a controllable refractive index. Such an approach allows for university grade development and testing of holographic computation methodology, but its limitations and drawbacks currently disable the massive application in consumer electronics. This chapter describes the differences between the behavior of the modulator as expected from Fourier optics and that observed in practical optical experiments. Moreover, practical hints and proven techniques of overcoming selected hardware issues of the chosen liquid-crystal-on-silicon (LCoS) phase modulators are given. The smart combination of the described techniques could allow more precise operation of spatial light modulators with a higher agreement with numerical simulations, especially for holographic projection of colorful images.

“…This technology is widely applied in a large number of optical applications and hence they have been employed as spatial light modulators (SLMs) in image processing, holography, data storage, programmable adaptive optics, medical optics, and diffractive optics. 1 Recently, a new type of reflective LCDs has been developed by employing liquid crystals of silicon (LCoS). These displays have awakened a great amount of interest among researchers due to their specific technical characteristics, which are superior in many aspects to the ones provided by transmissive LCDs.…”

4-[4'-Cyanophenoxy-carbonyl-phenyl-4-(trimethylsilyl)ethynyl]benzoate a rod shaped liquid crystal (SmA) is synthesized and characterized. The single-crystals were grown in triclinic crystal system in the space group of Pıwith unit cell parameters a = 5.9577(2) Å, b = 8.0398(3) Å, c = 25.8842(9) Å, α = 86.096(2) o , β = 89.912(2) o , γ = 2.919(2) o , Z = 2, and V = 1182.16(7). The crystal structure is stabilized by C-H•••O intra-molecular interactions. Further, the structure also involves C-H•••π interactions and weak π-π stacking interactions [centroid-centroid separation = 3.806 (3) Å].
