Abstract: A lens specification for multiple lens layers of a lens structure is generated by one or more processors. A multifocal correction (MFC) component is assigned to at least one lens layer of the multiple lens layers. Parameters are generated for a display optics (DO) lens layer comprising an augmented reality (AR) display, the DO lens layer having a first side for facing an eye of the user and a second side for facing away from the eye of the user. Parameters are generated for one or more eye side (ES) lens layers of the multiple lens layers to be disposed adjacent to the first side of the DO lens layer, and for one or more world side (WS) lens layers to be disposed adjacent to the second side of the DO lens layer. The generated lens specification is provided for use in production of the lens structure for the user.

The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lends around the photopolymer film; sandwiching photopolymer film in between two portions of a lens' applying photopolymer film to a concave surface of a lens' and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.

Abstract: A system includes a head-mounted display (HMD) device configured to project digital images to a user's eye and a viewing device. The viewing device includes an optical relay unit having a world-facing surface and an eye-facing surface and a holder coupled to the optical relay unit and configured to support the HMD device near the world-facing surface. The optical relay unit is configured to transmit light projected by the HMD device to an eye-facing aperture disposed at the eye-facing surface of the optical relay. The system shifts an eyebox of the HMD by receiving light projected from an optical combiner of the HMD, transmitting the light through the optical relay unit of the viewing device to the eye-facing aperture of the optical relay unit, and outputting the light from the eye-facing aperture such that the light is focused at an eyebox in which a user's eye is located.

The lens is fixed in position to the improvement in the quality of diffracted light achieving a defined threshold. The characteristic may include brightness.

Abstract: Systems, devices, and assemblies for implementing multi-focal lens portions in wearable heads-up displays are described. Multi-focal lens portions may include at least two regions having different optical power, and at least one transition region between regions having different optical power. If display light is directed through a transition region, aberrations or distortion may be visible in the display presented to the user. The present systems, devices, and assemblies address this issue through shaping, positioning, and orienting of regions of a multi-focal lens portion, through positioning, orientation, and aiming of display optics, and/or through arrangements of lens assemblies which prevent display light from travelling through a multi-focal lens portion.

Abstract: Systems, devices, and methods for wearable heads-up displays (WHUD) are described. A WHUD includes a front frame with two openings each with one recess which extends along at least a portion of the periphery of the openings, two arms including frame portions and temple portions, two lenses, a projector to generate light, and a holographic optical element (HOE) carried by a lens to redirect light to an eye of a user. Frame portions insert into the recesses and are held in place when the lenses are inserted into the recesses, wherein when the WHUD is assembled the projector and HOE are positioned correctly to create a display for the user. The assembled WHUD is inflexible where the front frame and arms are attached such that when worn the projector maintains a fixed position relative to the HOE and the display remains undistorted and visible to the user.

Abstract: Systems, devices, and methods for beam combining within laser projectors are described. A laser projector includes first, second, and third laser diodes to generate red, green, and blue laser light respectively, a controllable scan mirror, and a heterogeneous beam splitter system. The red, green, and blue laser light have distinct maximum powers. The heterogeneous beam splitter system splits at least one of the red, green, and blue laser light and combines respective first portions of all three into an aggregate beam. Second portions of laser light are excluded from the aggregate beam. At the maximum power of each laser light the aggregate beam is white as defined by a target white point. The heterogeneous beam splitter system directs the aggregate beam towards the controllable scan mirror which scans the beam onto a projection surface. Decreasing the power of the laser light post-generation provides a larger range of aggregate beam colors.

Abstract: Systems, devices, and methods for beam combining are described. A monolithic beam combiner includes a solid volume of optically transparent material having a planar input surface, an output surface, a planar reflector physically coupled to the solid volume, and at least a first planar dichroic reflector within the solid volume. Multiple light sources input light into the solid volume through the planar input surface such that each light beam from a respective source is initially incident on one of the planar reflector and the at least a first planar dichroic reflector. The light is reflected by and transmitted through the reflectors and an aggregate beam is created. Because the reflectors are within an optically transparent material the beam combiner can be made more compact than a conventional beam combiner. This monolithic beam combiner is particularly well suited for use laser projectors and in wearable heads-up displays that employ laser projectors.

An optical splitter includes a transparent polygonal structure having an input side to receive light from a light source and an output side that is segmented into multiple facets. Each facet is engineered to provide a respective planar surface that is oriented at a different angle in each of at least two spatial dimensions relative to the other facets in order to refract and route a respective portion of the light along a respective set of optical paths. The input side may be faceted as well to further refine the optical paths. A particular application of the polygonal structure in an optical splitter providing eyebox expansion by exit pupil replication in a scanning laser-based wearable heads-up display is described in detail.

Abstract: Systems, devices, and methods that integrate eye tracking capability into scanning laser projector (“SLP”)-based wearable heads-up displays are described. An infrared laser diode is added to an RGB SLP and an infrared photodetector is aligned to detect reflections of the infrared light from features of the eye. A holographic optical element (“HOE”) may be used to combine visible light, infrared light, and environmental light into the user's “field of view.” The HOE may be heterogeneous and multiplexed to apply positive optical power to the visible light and zero or negative optical power to the infrared light.
