  • Publication number: 20250093654
    Abstract: An occlusion-capable viewing device includes an imaging lens, a collimating lens, and a virtual display module, and between the imaging lens and the collimating lens, an image inverter, and a spatial light modulator. The imaging lens projects a first inverted image of a scene on to an entrance surface of the image inverter. The image inverter rotates the first inverted image to yield a first upright image. The spatial light modulator attenuates a first image-region of the first upright image to produce a modulated optical beam. The virtual display module includes a display device and a light combiner, which combines (i) the collimated optical beam and (ii) illumination emitted by the display device to yield an occluded image.

  • Publication number: 20250053018
    Abstract: Images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The waveguide stack may include multiple pluralities (e.g., first and second pluralities) of waveguides, each configured to produce an image by outputting light corresponding to a particular color. The total number of waveguides in the second plurality of waveguides may be less than the total number of waveguides in the first plurality of waveguides.

  • Patent number: 12204109
    Abstract: A tiled head-mounted display device, comprising: an optical component including a plurality of prisms with free-form surfaces, each prism being a wedge prism comprising a first optical surface, a second optical surface and a third optical surface; and a display component including a plurality of micro-displays, wherein the number of the micro-displays and the number of the prisms with free-form surfaces is identical. The tiled head-mounted display device according to the present invention is compact and light, provides wide field of view and high resolution, especially for the optical tiling head-mounted display device, the exit pupil planes of each display channels are coincident, thus avoiding pupil aberration and keeping exit pupil diameter and eye clearance same as the single ocular. There is no resolution variance throughout the entire field of view, thus preventing extra trapezoid distortion.

  • Patent number: 12039958
    Abstract: Devices and methods that use a perceptual-driven approach to foveated displays with the goal of offering elegant degradation of image resolution with the increase of eccentricity and eye movements. As a result, the implementation leads to minimally perceivable image artifacts and image resolution discontinuity, and may further eliminate or limit the need for an eyetracker or scanning mechanism. Hereby we refer this approach as perceptual-driven continuous foveated display in contrast to the multi-level discrete foveation approach used previously.

  • Patent number: 12001021
    Abstract: In a display system configured to display images at multiple depth planes, images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across the depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The stack of waveguides may include multiple pluralities of different numbers of waveguides, each plurality configured to produce an image by outputting light corresponding to a particular color. A display controller can introduce blur and/or change pixel size for images to be presented for at least one depth plane, based on the contents of images.

  • Patent number: 11885968
    Abstract: Compact occlusion-capable optical see-through head mounted displays (OCOST-HMDs) are described having a double-wrapped path and capable of rendering per-pixel mutual occlusion, and correct see-through viewing perspective or a pupil-matched viewing between the virtual and real views. An example device includes a polarizer, a polarizing beam splitter, an objective lens, a spatial light modulator (SLM), an eyepiece lens, a quarter wave plate, and a reflective optical element configured to reflect the light that is incident thereupon in a first direction, and to transit the light received from a microdisplay that is incident thereupon from a second direction. The components form a first double-pass configurations that allow the light that passes through the objective to reflect from the SLM and propagate again through the objective, and a second double-pass configuration that allows the light that passes through the eyepiece to reflect from the reflective optical element and propagate again through the eyepiece.

  • Patent number: 11803059
    Abstract: A display placed in an optical pathway extending from an entrance pupil of a person's eye to a real-world scene beyond the eye. The display includes at least one 2-D added-image source that is addressable to produce a light pattern corresponding to a virtual object. The source is situated to direct the light pattern toward the person's eye to superimpose the virtual object on an image of the real-world scene as perceived by the eye via the optical pathway. An active-optical element is situated between the eye and the added-image source at a location that is optically conjugate to the entrance pupil and at which the active-optical element forms an intermediate image of the light pattern from the added-image source. The active-optical element has variable optical power and is addressable to change its optical power to produce a corresponding change in perceived distance at which the intermediate image is formed, as an added image to the real-world scene, relative to the eye.
