    Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in scanning laser-based wearable heads-up displays ("WHUDs") are described. The WHUDs described herein each include a scanning laser projector ("SLP"), a holographic combiner, and an optical replicator positioned in the optical path therebetween. For each light signal generated by the SLP, the optical replicator receives the light signal and redirects each one of N > 1 instances of the light signal towards the holographic combiner effectively from a respective one of N spatially-separated virtual positions for the SLP. The holographic combiner converges each one of the N instances of the light signal to a respective one of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.

    Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays ("WHUDs") are described. A WHUD includes a scanning laser projector ("SLP"), a holographic combiner, and an exit pupil selector positioned in the optical path therebetween. The exit pupil selector is controllably switchable into and between N different configurations. In each of the N configurations, the exit pupil selector receives a light signal from the SLP and redirects the light signal towards the holographic combiner effectively from a respective one of N virtual positions for the SLP. The holographic combiner converges the light signal to a particular one of N exit pupils at the eye of the user based on the particular virtual position from which the light signal is made to effectively originate. In this way, multiple instances of the exit pupil are distributed over the eye and the eyebox of the WHUD is expanded.

    Abstract: Systems, devices, and methods for focusing laser projectors are described. A laser projector includes N ≥ 1 laser diodes, each of which emits laser light having a divergence. Each laser diode is paired with a respective primary or collimation lens to at least reduce a divergence of the laser light that the laser diode produces. Downstream from the primary lens(es) in the optical path(s) of the laser light, a single dedicated secondary or convergence lens converges the laser light to a focus. By initiating the convergence of the laser light at the secondary or convergence lens as opposed to at the primary or collimation lens(es), numerous benefits that are particularly advantageous in laser projection-based wearable heads-up displays are realized.

    Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays ("WHUDs") are described. A WHUD includes a scanning laser projector ("SLP"), a holographic combiner, and an optical splitter positioned in the optical path therebetween. The optical splitter receives light signals generated by the SLP and separates the light signals into N sub-ranges based on the point of incidence of each light signal at the optical splitter. The optical splitter redirects the light signals corresponding to respective ones of the N sub-ranges towards the holographic combiner effectively from respective ones of N spatially-separated virtual positions for the SLP. The holographic combiner converges the light signals to respective ones of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.
