摘要： PCT No. PCT/US94/05493 Sec. 371 Date Nov. 20, 1995 Sec. 102(e) Date Nov. 20, 1995 PCT Filed May 20, 1994 PCT Pub. No. WO94/28073 PCT Pub. Date Dec. 8, 1994Polarizing coatings are formed from dyestuffs which provide a stable liquid crystalline phase in a wide range of concentrations, temperatures and pH-values. Particles formed by aggregates of the liquid crystal molecules are oriented in a predetermined direction to polarize light. The stability of the liquid crystalline state allows orienting the particles by mechanical forces such as a shearing force applied when the liquid crystal (10) is spread on a support surface (20) by a knife-like doctor (90) or a tension deformation force acting on the meniscus of the liquid crystal deposited between two surfaces (20, 30) as the surfaces are peeled off one another. As a result, the polarizing coatings are formed in some embodiments by simple methods. In some embodiments, the polarizing coatings have a high lightfastness, a high thermal stability, and a high dichroic ratio.

摘要： The invention belongs to the class of thermostable and lightfast dichroic polarizers made using thin films of dichroic organic substances, in particular, the organic dyes in which molecules of a dichroic organic substance are ordered in a crystalline lattice and which are deposited onto either a rigid or a flexible substrate surface. The technical result consists in the fact of widening the spectral range of the polarizer operation and in simultaneous improvement of the polarizer's polarizing characteristics. The proposed dichroic polarizer is manufactured using the film which at least partially has the crystal structure and which contains at least one dichroic organic substance with the planar-structure molecules (or molecule fragments). The dichroic substance is selected such as to have at least one maximum in each of the following regions of the absorption spectrum curve: 400-700 nm and/or 200-400 nm, and 0.7-13 microns. The film order parameter S corresponding to at least one maximum in the 0.7-13 micron region of the absorption spectrum curve is no less than 0.88. This parameter is calculated from the expression where D ORTHOGONAL and D11 are the optical densities measured in the polarized light when, correspondingly, the polarizer's polarization axis is perpendicular and parallel, respectively, to the polarization plane of the spectrometer electromagnetic radiation.

摘要： An interferential optical filter is provided comprising multiple layers each having real and/or imaginary refraction indexes. The values of the real and imaginary indexes depend on the strength of an external electric field. The material refraction indexes and the thickness of each layer and their combination are selected such as to provide an interference extremum in at least one region of the spectrum, for at least one polarization of incident light. At least one layer is made of an electro-optical material, which is anisotropic and made from at least one aromatic organic material. The molecules or fragments of molecules of the aromatic organic material have a flat structure. At least part of the layer of the electro-optical material has a crystalline structure with an intermolecular spacing of 3.4±0.3 Å along one of optical axes.

摘要： A liquid crystal shutter is provided comprising at least two liquid crystal cells and at least three polarizers (101, 108, 109, 116). Each of the liquid crystal cells contains a plurality of layers between two substrates (102, 107, 110, 115) and is disposed between two adjacent polarizers. The adjacent two liquid crystal cells have substantially equal absolute values and opposite directions of twist angles. The liquid crystal shutter of the invention substantially increases the viewing angle and the contrast ratio at large viewing angles, provides a symmetrical dependence of the contrast ratio on the viewing angle, and decreases the switching time as well as the driving voltages. The shutter provides substantially improved angular characteristics, high contrast ratio, good transparency in the light state, and a fast switching time.
