摘要： Optical devices based on novel components for selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the previous (parent) patents are herein made both more useful in practical day-to-day use and more widely applicable to improving the ability of a user to perceive visual stimuli.

摘要： Provided is a multi-image display apparatus including a light source configured to emit light, a spatial light modulator configured to modulate the light emitted by the light source and generate image light, a first optical system configured to deliver the image light through a first light path and a second light path that is not parallel with the first light path, and a second optical system configured to deliver external light and the image light delivered through the second light path to a pupil of a viewer, through a third light path that is not parallel with the second light path, wherein the second optical system includes a steering optical device provided at a crossing point of the second light path and the third light path and configured to be two-axis rotated.

摘要： An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

摘要： The present disclosure related generally to techniques for improving the performance and efficiency of display systems, such as laser scan beam display systems or other types of display systems (e.g., micro-displays). Display systems of the present disclosure may include a polarization compensation optic, such as a spatially varying polarizer, that provides phase retardation that varies as a function of position, which provides polarization compensation to provide light that is well suited for a polarization sensitive optic of the display system, such as a waveguide-based optical system, a pancake optical system, a birdbath optical system, a coating-based optical system, etc. The display systems of the present disclosure may be components of head-mounted display systems, or other types of display systems.

摘要： Methods, systems and apparatuses may provide for technology that identifies a seam area between a pair of images corresponding to a first eye and determines a disparity between the seam area and a reference area at a center line of a reference image corresponding to a second eye. The technology may also automatically adjust one or more pre-stitch parameters of camera sensors associated with the pair of images and the reference image based on the disparity.

摘要： A 3D image pixel in a spatially multiplexed stereo 3D display includes a first left-eye subpixel and a second left-eye subpixel that are both driven when displaying the left-eye image. The 3D image pixel also includes a first right-eye subpixel and a second right-eye subpixel that are both driven when displaying the right-eye image. The subpixels may all have a square shape. Single color emitters in the subpixels of the same eye may be driven by the same electronics. A 3D image pixel in a second spatially multiplexed stereo 3D display includes a left-eye pixel driven when displaying the left-eye image and a right-eye pixel driven when displaying the right-eye image. The pixels may all have a rectangular shape, and the horizontal measurement of the pixels may be greater than the vertical measurement of the pixels.

摘要： The present invention is directed to an indirect ophthalmoscopic system for imaging of the ocular fundus including a headband configured to hold a digital imaging device and a plus eyepiece lens in front of an eye of the examiner, with the plus eyepiece lens positioned in between the digital imaging device and the examiner's eye, such that the examiner is focused upon the display of the digital imaging device. The aperture of the digital imaging device receives light reflected from the ocular fundus of the patient's eye, emanating from the patient's pupil. The examiner examines the patient and composes the image of the ocular fundus directly in the display screen. In this way, what the examiner sees is captured by the digital imaging device. Stereoscopic imagery is obtained by optical means that create side-by-side virtual images of the aperture of the digital imaging device within the pupil of the eye.
