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.

Abstract: Systems, devices, and methods for eyebox expansion in wearable heads-up displays (WHUD) are described. A WHUD includes a support structure, a scanning laser projector (SLP), a split mirror, an optical splitter, and a holographic combiner. When the WHUD is worn on the head of a user the holographic combiner is positioned in a field of view of the user. The SLP scans light signals onto the split mirror which reflects the light signals onto the optical splitter. The optical splitter redirects the light signals towards the holographic combiner such that subsets of the light signals originate from spatially-separated virtual positions. The holographic combiner redirects the light to the eye resulting in spatially-separated exit pupils. The spatial separation of the exit pupils results in an expanded eyebox. The indirect path of light from SLP to optical splitter enables a smaller and therefore more aesthetically desirable design for the WHUD.

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.

Abstract: An articulated temple includes a temple arm, a temple end piece, and a hinge having a first hinge leaf coupled to the temple arm and a second hinge leaf coupled to the temple end piece. A pivot joint having a pivot axis is formed between the first and second hinge leaves. Each of the temple arm and temple end piece has a top curved edge. The top curved edges are concentric about the pivot axis provided by the hinge to enable one of the curved edges to move relative to the other curved edge along a portion of a circular path when the temple end piece is pivoted relative to the temple arm about the pivot axis. An eyewear including the articulated temple is disclosed.

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.
