An optical system for light energy concentration may comprise a light concentrator to convert incident light to converging light, a light collimating element to receive the converging light and to reduce an angle of convergence of the converging light, and a light directing element to direct the reduced-angle converging light to a light guide to transmit the directed light.

Method and device for concentrating, collimating, and directing light

An image projector for augmenting the appearance of a physical object is disclosed, also known as an augmented reality projector. The augmented reality projector comprises an optical arrangement to provide the possibility of precise matching of a projected image of the physical object back onto the object itself, instead of using digital image processing to do so. Digital image processing may be used to enhance features of the image and is not required for resizing or orienting the image to the object. This reduces the need for computational power to process the image and spares processing resources to refresh the image in real time. Accordingly, the processed image can be refreshed to change the appearance of a moving object. Furthermore, the precise matching provides the possibility of using projected images a graphical use interface, as movements of a user's fingers on the interface can be determined accurately.
