  • Patent number: 10031338
    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.

  • Patent number: 9989764
    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.

  • Publication number: 20180129058
    Abstract: Systems, devices, and methods for field shaping in wearable heads-up displays (WHUD) with laser projectors are described. A WHUD includes a support structure carrying a laser projector, a field shaper optic, and a transparent combiner to combine the projected laser light and environmental light. The laser projector generates a laser light having a field. The laser light is scanned through the field shaper optic and over the transparent combiner. The field shaper optic heterogeneously varies the focal length of the laser light depending on the laser light properties to alter the field of the laser light to approximately match a shape of the transparent combiner. The transparent combiner redirects the laser light to a field of view of a user to create a focused image at an eye of the user.

  • Publication number: 20180129052
    Abstract: Systems, devices, and methods for preventing image astigmatism in wearable heads-up displays (WHUD) with laser projectors are described. A WHUD includes a support structure carrying a laser projector and an eyeglass lens with a transparent combiner. The laser projector includes at least one laser diode, at least one anamorphic optical element, and at least one controllable mirror. The at least one laser diode generates a laser light that, without optical manipulation, would result in an astigmatic, unfocused image at the eye of the user. The at least one anamorphic optical element anamorphically shapes the spot of the laser light to compensate for an astigmatic effect of at least the transparent combiner. The at least one controllable mirror scans the light onto the transparent combiner and the transparent combiner redirects the light towards an eye of a user to create a focused, non-astigmatic image.

  • Publication number: 20180129057
    Abstract: Systems, devices, and methods for beam shaping in wearable heads-up displays (WHUD) with laser projectors are described. A WHUD includes a support structure carrying a laser projector and an eyeglass lens with a transparent combiner. The laser projector includes at least one laser diode, at least one anamorphic optical element, and a controllable mirror having a reflective area. The at least one laser diode generates laser light having a spot area with at least one dimension being smaller or larger than the dimensions of the reflective area of the controllable mirror. The at least one anamorphic optical element anamorphically reshapes the spot area such that the second spot area has approximately the same dimensions as the controllable mirror. The controllable mirror scans the reshaped laser light over the transparent combiner, which redirects the light, creating a focused image at the eye of the user with minimal loss of laser light.

  • Publication number: 20180113305
    Abstract: Systems, devices, and methods for laser projectors with variable luminance that are well-suited for use in a wearable heads-up display (“WHUD”) are described. Such laser projectors include a laser light source(s) and a scan mirror(s) to generate an image in the field of view of a user, and a liquid crystal element between the light source(s) and the scan mirror(s) to adjust the luminance of the image. The liquid crystal element is on an optical path between the laser light source(s) and the scan mirror and is communicatively coupled to a controller that modulates an opacity of the liquid crystal element. The opacity of the liquid crystal element determines the luminance of the image and may be altered in response to different factors, such as ambient light. Particular applications of the laser projector systems, devices, and methods in a wearable heads-up display are described.

  • Publication number: 20180107103
    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.

  • Publication number: 20180095213
    Abstract: Systems, devices, and methods for making, replicating, and using curved holographic optical elements (“HOEs”) are described. A hologram may be optically recorded into a planar layer of holographic film with various measures in place to compensate for changes (e.g., in optical power and/or playback wavelength and/or angular bandwidth) that may result when a curvature is subsequently applied thereto. A hologram may be optically recorded into a curved layer of holographic film with various measures in place to compensate for optical effects of a curved transparent substrate upon which the holographic film is mounted. A curved HOE may be returned to a planar configuration to undergo holographic replication or holographic replication may be performed using a curved master HOE and curved “recipient” film. The curved HOEs described herein are particularly well-suited for use when integrated with a curved eyeglass lens to form the transparent combiner of a virtual retina display.

  • Publication number: 20170212349
    Abstract: Systems, devices, and methods for spatial multiplexing in holographic optical elements (“HOEs”) are described. A spatially-multiplexed HOE includes multiple spatially-separated holographic regions and each spatially-separated region applies a respective optical function to light that is incident thereon. An exemplary application as a spatially-multiplexed holographic combiner (“SMHC”) in a scanning laser-based wearable heads-up display (“WHUD”) is described. In this exemplary application, a scanning laser projector directs multiple light signals over the area of the SMHC and the SMHC converges the light signals towards multiple spatially-separated exit pupils at or proximate the eye of the user. The particular exit pupil at the eye of the user towards which any particular light signal is converged by the SMHC depends on the particular region of the SMHC upon which the light signal is incident.
