Abstract	本发明公开了一种波导型液晶的激光扫描控制方法，包括以下步骤：(1)在液晶层上方设置电极驱动层，在所述电极驱动层上设置若干独立控制的电极，所述电极一端设置激光角度控制部，所述激光角度控制部包括入射边和出射边，使所述入射边和出射边均为直边且彼此或者彼此的延长线相交。(2)将若干独立控制的电极沿激光入射方向分别设置为第零级电极、第一级电极……第N极电极；(3)根据需要偏转的角度，选择第零级至第N级偏转电极施加正性或者负性电压；(4)待第N级偏转电极下的液晶层达到满偏时，撤除正性或者负性电压。本发明根据波导型液晶的特性，可以提前计算电极上的电压施加方式，从而能够快速实现波导型液晶的连续激光扫描。
Other Abstract	The invention discloses a laser scanning control method for waveguide type liquid crystals. The method comprises the following steps of (1) arranging an electrode driving layer above a liquid crystallayer and arranging a plurality of independently controlled electrodes on the electrode driving layer, wherein one end of each electrode is provided with a laser angle control part and each laser angle control part comprises an incoming edge and an outgoing edge to ensure that both the incoming edge and the outgoing edge are straight edges and are mutually intersected or extension cords of the incoming edge and the outgoing edge are intersected; (2) respectively arranging the plurality of independently controlled electrodes as a zero-level electrode, a first-level electrode, ..., an N-level electrode along the laser incidence direction; (3) selecting the zero-level to the N-level deflection electrodes to apply positive or negative voltage according to a to-be-deflected angle; and (4) removing the positive or negative voltage when the liquid crystal level under the N-level deflection electrode achieves full deflection. The method is capable of calculating the voltage application manneron the electrodes in advance according to the characteristics of the waveguide type liquid crystals, so as to rapidly realize the continuous laser scanning of the waveguide type liquid crystals.
