TLDR
A new optical device whose reflection intensity can be electrically controlled at specific wavelengths has been demonstrated that has a liquid-crystal/polymer multilayer structure formed by holography.Abstract:
— A new optical device whose reflection intensity can be electrically controlled at specific wavelengths has been demonstrated. This device has a liquid-crystal/polymer multilayer structure formed by holography. The diffraction efficiency for Ar-laser light is about 70%. The reflection intensity can be electrically controlled with a response time of less than 1 ms.read more

Holographic Polymer-Dispersed Liquid Crystals (H-PDLCs)1
TL;DR: In this paper, the formation of switchable holographic gratings from polymer-dispersed liquid crystals (H-PDLCs) allows for the development of turnable transmissive and reflective diffractive optics, created by coherent interference of laser radiation within a syrup containing photoreactive monomer, initiator, and liquid crystal.

Method of and apparatus for viewing an image
TL;DR: In this paper, a dynamic optical element (12) is used as a lens to follow the eye gaze as its direction alters, and the dynamic lens is controlled in dependence on this to create an area of high resolution centred on the direction of gaze.

Polymer as an important component of blends and composites with liquid crystals
TL;DR: In this article, a review of various ways of preparation of liquid crystal/polymer blends and composites leading to their required applications is presented. But the most important features of polymers which can be used as components of blends or composites with liquid crystals include: their film formation ability, high transparency, amorphicity, inertness in relation to a liquid crystal, good miscibility with liquid state and immiscibility in a solid state.
