摘要
A speckle reduction system is provided and includes a speckle reduction component and a control module. The speckle reduction component includes electrode layers and a liquid crystal layer. The liquid crystal layer is disposed between the electrode layers and configured to receive light from a coherent light source. The control module is configured to (i) supply a first voltage signal having a first voltage to the electrode layers to provide a first speckle pattern output, and (ii) supply a second voltage signal having a second voltage to the electrode layers to provide a second speckle pattern output, wherein the first voltage and the second voltage are greater than zero. The control module is configured to transition between providing the first voltage signal and the second voltage signal in less than at least one of half an integration time of a human eye or 8 milliseconds.
