Abstract

FIELD: optical instrumentation, specifically study and optimization of dynamic properties of liquid crystal cells used in holographic systems of optical information recording and in projection television systems as aid to enter and process information. SUBSTANCE: for realization of proposed proximate method of determination of initial inclination angle of molecules in liquid crystal normal incidence of light beam in plane of liquid crystal cell with rigid attachment of the latter and pulse supply voltage of sample with pulse duration much more than re-orientation time of molecules in liquid crystal are used which enables contribution of polarization phenomena and hysteresis in operation of liquid crystal cell to be levelled. EFFECT: simplification of technique of determination of initial incidence angle of liquid crystal molecules by extrapolation of lower section of transmission curve. 2 dwg, 1 tbl

Изобретение относится к оптическому приборостроению, в частности к исследованию и оптимизации динамических свойств ЖК ячеек и ЖК-ПВМС, используемых в голографических системах записи оптической информации и в системах проекционного телевидения в качестве устройств ввода и обработки информации. Цель: упрощение методики определения начального угла наклона ЖК молекул путем экстраполяции нижнего участка кривой пропускания. При реализации предлагаемого способа определения начального угла наклона ЖК молекул используют нормальное падение светового луча в плоскости ЖК ячейки при жестком закреплении последней и импульсное напряжение питания образца с длительностью импульса много большей, чем время переориентации ЖК молекул, что позволяет нивелировать вклад поляризационных явлений и гистерезиса в работе ЖК ячейки.The invention relates to optical instrumentation, in particular to the study and optimization of the dynamic properties of LCD cells and LCD PVMS used in holographic optical information recording systems and in projection television systems as input and processing information devices. Purpose: simplification of the method for determining the initial angle of inclination of LC molecules by extrapolating the lower portion of the transmission curve. When implementing the proposed method for determining the initial angle of inclination of LC molecules, the normal incidence of the light beam in the plane of the LC cell is used when the latter is rigidly fixed and the pulse supply voltage of the sample with a pulse duration is much longer than the reorientation time of the LC molecules, which makes it possible to level out the contribution of polarization phenomena and hysteresis to the work LCD cells.
