  • Patent number: 11199716
    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.

  • Patent number: 11030973
    Abstract: Systems, devices, and methods for detecting ambient light with wearable heads-up displays are described. An ambient light sensor can be positioned close to a user's eye area on a user-side of a wearable heads-up display. By positioning the ambient light sensor on a user-side of the wearable heads up display, the ambient light sensor can be in a position and/or orientation which receives ambient light in a similar manner a user's eye, and thus ambient light detection can be more accurate. Brightness of display light output by the wearable heads-up display can be adjusted in response to the detected brightness of ambient light.

  • Patent number: 10718951
    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.

  • Patent number: 10663732
    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.

  • Publication number: 20200133001
    Abstract: Systems, devices, and methods to perform alignment in a projector are described. Laser light emitted is directed to at least one lens, which directs the laser light to a diffractive optical element (DOE), which produces a diffracted light. A sensor measures a property of the diffracted light, and a position of at least one lens adjusted to improve a quality of the diffracted light. The lens is fixed in position to the improvement in the quality of diffracted light achieving a defined threshold. The characteristic may include brightness.

  • Patent number: 10613331
    Abstract: Systems, devices, and methods for optical splitters are described. 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.

  • Patent number: 10534182
    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.
