Lasers offer highly desirable characteristics for imaging and display applications, including high directionality, intensity, and potential for a wide color gamut. However, the coherence of laser light leads to the formation of speckle, a spatially distributed granular distortion caused by interference. In this presentation, we demonstrate novel liquid crystal (LC) active screens that enable a significant reduction in the speckle noise for RGB laser illumination sources. The advantages of the active screen approach are then highlighted in comparison to LC speckle reducers used in transmissive geometries. We conclude by considering the impact of the active screen configuration on image formation.
