    • The invention concerns a switch for optical beams comprising a series of optical input channels (110. , 150) and a series of optical output channels (410, , 450), two liquid crystal cells, respectively adapted to deflect an optical beam coming out of an input channel (110, , 150) or arriving onto an output channel (410, , 450), said two cells comprising each a series of electrodes adapted to orient liquid crystals when one such electrode is subjected to a supply voltage, said electrodes being distributed in zones (210, , 250, 310, , 350), each zone corresponding to a single input channel (110, , 150) or a single output channel (410, , 450), the switch further comprising means for supplying the electrodes with selected voltages. The invention is characterised in that it comprises a series of separate electronic circuits, each being connected to at least a different zone (210, 250) of a given cell, said circuits being each capable of transforming a respective control signal indicating a channel to be coupled to the channel of said zone (210, , 250, 310, , 350) into a series of supply voltages for the electrodes of the zone (210, , 250, 310, , 350).
    • 本发明涉及一种用于光束的开关,其包括一系列光输入通道(110.,150)和一系列光输出通道(410,450),两个液晶单元分别适于偏转出来的光束 输入通道(110,150)或到达输出通道(410,450),所述两个单元包括一系列电极,其适于在一个这样的电极经受电源电压时定向液晶,所述电极为 分布在区域(210,22,310,350)中,每个区域对应于单个输入通道(110,150)或单个输出通道(410,450),所述开关还包括用于提供电极 选择电压。 本发明的特征在于它包括一系列单独的电子电路,每个电子电路连接到给定单元的至少不同区域(210,250),所述电路各自能够将指示频道的相应控制信号变换为 耦合到所述区域(210,...,250,310,350)的通道,以形成用于区域(210,,250,310,350)的电极的一系列电源电压。
