Speckles in images formed by a laser beam are interference noise arising due to coherent nature of laser radiation. As the number of projection systems using laser light sources increases, new methods and devices appear for reducing the contrast of s

This is a review of results from studying ferroelectric liquid crystals (FLCs) of a new type developed for fast low-voltage displays and light modulators. These materials are helix-free FLCs, which are characterized by spatially periodic deformation

A video projector with liquid crystal microdisplay based on FLCoS- structure is considered, and the new low-voltage ferroelectric liquid crystal (FLC) with a compensated helix as an electro-optical material providing physically realizable continuous

We suggest a simple and effective method of suppressing the speckle-noise in the lasergenerated images using the high-speed electro-optical cell with the ferroelectric liquid crystal (FLC), in which the helix is absent (compensated). The nature of de

We have studied the method for suppressing speckle noise in patterns produced by a laser based on a fast-response electro-optical cell with a ferroelectric liquid crystal (FLC) in which helicoid is absent, i.e., compensated for. The character of smec

Electro-optical response of a display cells with novel helix-free FLC (differently, compensated helix ferroelectric—CHF) is considered. Predominance of the shear viscosity in the soliton mode of FLC director reorientation leads to weakening the tem

Selection of the essential parameters and conditions of molecules reorientation in non-helix FLC allowed to reduce the optical response time of a display cell to 24 μs and to increase the frequency of light modulation in the soliton mode up to 7 kHz
