“…Thus, with the outstanding optical quality (with high contrast and no diffraction) and fast electro‐optical modulation, the ESHFLCs are characterized by the binary high quality optical shutter that can be deployed for the display applications. However, because of the binary amplitude modulation such display demands digital driving unlikely analog driving for the conventional LCDs where the gray scale is controlled by the amplitude of the driving voltage . Thus, the gray scale can be generated either by the pulse width modulation or by the multiple pulse modulation of the driving signal.…”

The ferroelectric liquid crystals, because of their fast electro‐optical response, are one of the most important classes of liquid crystals. Here, in this review, we have summarized the different electro‐optical modes for ferroelectric liquid crystals. Clark–Lagerwall effect (surface stabilized ferroelectric liquid crystal), deformed helix ferroelectric (DHF) effect, electrically suppressed helix (ESH) mode, DHF orientational Kerr effect, and ESH diffraction modes have been discussed. All of the crucial features, that is, optics, electro‐optics, dynamics, and their dependence on material parameters, operational regime, and applications, have been reviewed.

“…Durch die rapide Entwicklung der Technologie erschließen sich für moderne FK-Displays aufgrund der großen Anzahl der Bildpunkte und der verbesserten optischen Eigenschaften zahlreiche neue Applikationen [l, 2,3]. Mit der fortschreitenden Miniaturisierung der Bildpunkte eröffnen sich neue Einsatzmöglichkeiten für LCDs in der optischen Datenund Informationsverarbeitung [4,5].…”

Übersicht:Flüssigkristallzellen sind sowohl zur Ampitudenmodulation als auch zur Phasenmodulation von Licht geeignet und damit als optische Elemente zur steuerbaren Lichtbeugung einsetzbar. Transparente Flüssigkristall-Phasenmodulatoren eignen sich in besonderem Maße zur Beugung hoher Lichtströme. Verschiedene Zelltechnologien, wichtige Parameter der Flüssigkristallzelle und die daraus resultierenden elektrooptischen Eigenschaften werden diskutiert und experimentelle Ergebnisse dargestellt.Abstract: Liquid crystal cells are suited for amplitude modulation as well as for phase modulation of light. Therefore these devices can be applied as optical elements for controlled diffraction of light. Transparent liquid crystal phase modulators are efficient tools for the diffraction of high light currents, especially. Different technologies, important design parameters and the resulting electro-optical properties are discussed and experimental data are outlined.Für die Dokumentation: Phasenmodulatoren / Adaptive optische Elemente / Elektrooptik / LCD / Spatial light modulator / Steuerbare Lichtbeugung
