    Abstract: Various embodiments are generally directed to techniques for image projection, such as in a computer-mediated reality system, for instance. Some embodiments are particularly directed to a computer-mediated reality system that is able to create an eyebox array for viewing images or sequences of images (e.g. video), the eyebox array created by reflecting projected images with a field imaging display. In some embodiments, the computer-mediated reality system may include a wearable frame, such as eyeglasses, to enable a user to utilize the computer-mediated reality system. For instance, the wearable frame may position the field imaging display such that different eyeboxes in the eyebox array come into focus as the user shifts their eyes between different directions of gaze.

    Abstract: Disclosed herein are devices and techniques related to optical diffusers and particularly, diffusers to reduce moire patterns in a projected image. The device may comprise an array of micro-focal elements or reflectors and a light polarization grid. The light polarization grid configured to change a polarization between portions of a light beam and the micro-focal elements of reflectors to diffuse the light beam such that portions of the light beam having a difference in polarization may meet at a point.

    Abstract: According to the present invention there is provided a projection device (30,50,100) comprising, a light source (31,61) which can provide light beams (32a,b,c 62a,b,c), wherein the light beams (32a,b,c 62a,b,c) can be used to define one or more pixels of a virtual image (48); a MEMS micro mirror (34) which is arranged to receive the light beams (32a,b,c 62a,b,c) provided by the light source (31,61), and wherein the MEMS micro mirror (34) can oscillate about at least one oscillation axis (7,17) to scan the light beams (32a,b,c 62a,b,c); a reflective element (38), which comprises a plurality of convex reflective projections (39), and wherein the reflective element (38) is arranged so that light beams (32a,b,c 62a,b,c) reflected by the MEMS micro mirror (34) are incident on said convex reflective projections (39), so that the light beams (32a,b,c 62a,b,c) are reflected by the convex reflective projections (39); a beam combiner (45,81), wherein the beam combiner is arranged to receive the light beams (32a,b,c 62a,b,c) which are reflected by the convex reflective projections (39) wherein the beam combiner (45,81) is configured to at least partially reflect the light beams (32a,b,c 62a,b,c) which it receives so that the light beams (32a,b,c 62a,b,c) can form a virtual image (48) which is visible when viewed from within an eyebox (47). There is further provided a corresponding method of projecting a virtual image.
