Abstract
A device for redirecting light may comprise a plurality of liquid prisms configured to transmit incident light from an image display element. The liquid prisms may be configured to selectively modulate a direction of the transmitted light relative to the incident light so as to selectively alter an angle at which an image generated by the image display element is projected to an observer. A method for redirecting light may comprise transmitting incident light from an image display element through a plurality of liquid prisms and selectively modulating a direction of the transmitted light relative to the incident light so as to selectively alter an angle at which an image generated by the image display element is projected to an observer.
