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.

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.

Such transparent displays include one or more scanning projector(s) that is/are mounted on or proximate the lens portion(s) thereof, directly in the field of view of the user.

Successive portions of the image are generated in rapid succession until the entire image is displayed to the user by projection directly onto the eye of the user from one or more point(s) within the user's field of view.

Abstract: Methods and systems to provide baseline measurements for aging compensation for a display device are disclosed. An example display system has a plurality of active pixels and a reference pixel. Common input signals are provided to the reference pixel and the plurality of active pixels. The outputs of the reference pixel is measured and compared to the output of the active pixels to determine aging effects. The display system may also be tested applying a first known reference current to a current comparator with a second variable reference current and the output of a device under test such as one of the pixels. The variable reference current is adjusted until the second current and the output of the device under test is equivalent of the first current. The resulting current of the device under test is stored in a look up table for a baseline for aging measurements during the display system operation.

Abstract: Systems, devices, and methods for transparent displays that are well-suited for use in wearable heads-up displays are described. Such transparent displays include a light source that sequentially generates pixels or other discrete portions of an image. Respective modulated light signals corresponding to the respective pixels/portions are sequentially directed towards at least one dynamic reflector positioned on a lens of the transparent display within the user's field of view. The dynamic reflector (such as a MEMS-based digital micromirror) scans the modulated light signals directly over the user's eye and into the user's field of view. Successive portions of the image are generated in rapid succession until the entire image is displayed to the user.

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.

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.
