摘要

1. The method of controlling the amplitude and direction of the electric field in the liquid crystal layer, characterized in that they use a system of at least four planar interdigital electrodes located on the inner surfaces of the substrates on both sides of the liquid crystal layer, the sign of the potential being arbitrary in time form switch on the electrodes using an analog-digital device, providing at certain points in time the planar and normal direction of the electric field of a given amplitude. 2. A device for controlling the amplitude and direction of the electric field in the liquid crystal layer, containing inputs U, TTL and outputs A, B, C, D, in which the arbitrary-time potential φ (t) set at the input U is switched at outputs A, B, C, D, which are connected to the respective four electrodes of the liquid crystal cell, by changing the logical state (0 or 1) at the TTL input in accordance with the following state table: 3. A liquid crystal light modulator containing a layer of liquid crystal between substrates with planar systems of electrodes and orienting films on their internal surfaces, and having means for distinguishing between switched states of transmitted light, characterized in that the switching of states of the liquid crystal is realized as a result of changing the amplitude and direction of the electric field in the liquid crystal layer, defined by the distribution of potentials on planar electrodes. 4. The liquid crystal modulator according to claim 3, characterized in that for controlling the amplitude and direction of the electric field in the liquid layer
