Abstract
A controllable device for phase modulation of coherent light comprises a modulator matrix having a plurality of liquid crystal modulator cells each being adapted to modulate a phase value of light passing through a liquid crystal modulator cell depending on a voltage, which is applied to the liquid crystal modulator cell; at least one polarity area of said modulator matrix including at least one liquid crystal modulator cell; at least one storage unit for storing at least one pair of voltage values of which one has a positive and the other has a negative polarity for the liquid crystal modulator cells, whereby the pair of voltage values corresponds to a predetermined phase value; and a control unit for selectively applying one pair of voltage values to one liquid crystal modulator cell.
