Abstract: An image projector with a high optical efficiency projects an image at an arbitrary distance from an observer. The image projector includes an illumination module having at least one spatially coherent light source; a phase image generator with an array of optical phase shifting elements; an electronic image controller connected electrically to the phase image generator; and a waveguide which includes at least one embedded partial reflector. The waveguide may be positioned either between the illumination module and the waveguide, or between the waveguide and the observer. The phase image generator may include phase shifts for canceling speckle, correcting optical aberrations, and/or compensating interference caused by light rays having different optical path lengths.

Abstract: In an embodiment, an apparatus is disclosed that includes at least one processor configured to determine a target portion of an eye motion box and to identify a facet of a light-guide optical element that is configured to direct a light beam comprising at least a portion of an image field of view toward the target portion of the eye motion box. The at least one processor is configured to identify a display region of an image generator that is configured to inject the light beam into the light-guide optical element at an angle that, in conjunction with the identified facet, is configured to direct the light beam toward the target portion of the eye motion box. The at least one processor is configured to selectively activate the identified facet and the identified display region to direct the light beam toward the target portion of the eye motion box.

Abstract: A method of fabricating a compound light-guide optical element (LOE) is provided. A bonded stack of a plurality of LOE precursors and a plurality of transparent spacer plates alternating therebetween is bonded to a first optical block having a plurality of mutually parallel obliquely angled internal surfaces. The block is joined to the stack such that first plurality of partially reflective internal surfaces of the block is non-parallel to the internal surfaces of the LOE precursor. After bonding, a second optical is thereby formed. At least one compound LOE is sliced-out of the second optical block by cutting the second block through at least two consecutive spacer plates having a LOE precursor sandwiched therebetween.

Abstract: A display for providing an image to an eye of an observer is disclosed. An image generator provides image illumination corresponding to the image to a substrate having mutually-parallel major external surfaces for propagation within the substrate. An intermediate optical arrangement including at least one astigmatic optical element directs the image illumination from the image generator so as to propagate within the substrate in a first in-plane direction by internal reflection. A reflective optical arrangement having cylindrical optical power reflects the image illumination so as to propagate in a second in-plane direction by internal reflection. A coupling-out arrangement couples out the collimated image illumination towards an eye of an observer. The intermediate optical arrangement includes an element deployed to generate a corrective optical aberration that at least partially cancels out with a characteristic aberration introduced by the reflective optical arrangement.

Abstract: A method for producing light-guide optical elements (LOEs) (16, 18, 56, 58) each having a set of mutually-parallel partially-reflecting surfaces (17) located between, and oriented non-parallel to, a pair of major external surfaces, and at least one region (30a, 30b, 30c) without partially-reflecting surfaces. The method includes bonding together parallel-faced plates (4) at interfaces to form a stack (42) of plates with partially-reflecting coatings between them. The stack is cut and polished to form a boundary plane (48, 48a, 48b) intersecting the interfaces, and a block (50, 50a, 50b) of transparent material is bonded to the stack. The resulting precursor structure (52, 52′) is sliced along parallel planes to form slices, each containing a part of the stack for the active region of the LOE and a part of the block.

Abstract: In an embodiment, an apparatus is disclosed that includes at least one processor. The at least one processor is configured to select a light source from a plurality of lights sources based at least in part on a location of a pupil of an eye relative to an eye motion box. The selected light source is configured to illuminate a portion of the eye motion box that corresponds to the location of the pupil with a light beam. The at least one processor is further configured to activate the selected light source to illuminate the portion of the eye motion box.
