System and methods for using modified driving waveforms to inhibit acoustic noise during driving of a liquid crystal polarization rotator

A system for operating a liquid crystal device, comprising:

• a liquid crystal device comprising a liquid crystal addressable element;
• a voltage source which increases, during use, a voltage provided to a driven level to the liquid crystal addressable element of the liquid crystal device, wherein said increase is performed over a time period greater than 1 ms, and wherein the liquid crystal addressable element is in a driven state at the driven level;
• and
• wherein the voltage source reduces, during use, the provided voltage to a relaxed level, wherein the liquid crystal addressable element is in a relaxed state at the relaxed level;
• and
• wherein said increase of the voltage over the time period to the driven level results in a reduced acoustical noise associated with the provided voltage.

A non-transitory computer readable storage medium containing program instructions executable to perform:

• increasing a voltage provided to a driven level to a liquid crystal addressable element of the liquid crystal device, wherein said increasing is performed over a time period greater than 1 ms, and wherein the liquid crystal addressable element is in a driven state at the driven level;
• and
• reducing the provided voltage to a relaxed level, wherein the liquid crystal addressable element is in a relaxed state at the relaxed level;
• wherein said increasing the voltage over the time period to the driven level results in a reduced acoustical noise associated with the provided voltage.
