A display system comprising a foveal display having a monocular field of view of at least 1 degree is positioned within a scannable field of view of at least 20 degrees, the foveal display positioned for a user. In one embodiment, the foveal display is positioned for the user's fovea.

Steerable high-resolution display

A system including an optical path length extender (OPLE) having two light paths having different path lengths, such that light entering the OPLE with a first polarization is directed through a first light path, and light entering the OPLE with a second polarization is directed through a second light path through the OPLE. The OPLE includes a first polarization sensitive reflective element at a first angle to the light entering the OPLE and a second angled polarization sensitive reflective element at a second angle to the light entering the OPLE, the second angled polarization sensitive reflective element intersecting the first polarization sensitive reflective element.

Polarized light direction system

A display system comprising a steerable display having a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees, the steerable display positioned for a user. In one embodiment, the steerable display is positioned for the user's fovea.

Steerable positioning element

A near-eye display system comprising an image source, a modulation stack, and an imaging assembly. The modulation stack, in one embodiment, comprises one or more digital light path length modulators.

Near-eye display system

A digital light path length modulator includes an optical path length extender (OPLE) and a polarization modulator. The OPLE has two light paths with different path lengths, such that the light having a first polarization is directed through a first light path, and the light having a second polarization is directed through a second light path.

A relative position based eye tracking system includes a light source to illuminate a portion of the eye and an optical sensor to capture a sequence of samples of the portion of the eye. The system further includes a sample comparator to compare two samples and a relative position calculator to calculate a change in the position of the eye based on data from the sample comparator.

Binocular display with digital light path length modulation

A method of measuring the thickness of an ophthalmic lens includes forming an ophthalmic lens over a convexly curved surface of a forming optic, the ophthalmic lens including a light absorptive component, and with the ophthalmic lens remaining over the convexly curved surface of the forming optic, measuring the thickness of the ophthalmic lens using information about the light absorptive component of the ophthalmic lens and an intensity reference value associated with the forming optic. The method includes passing light having a wavelength through the ophthalmic lens and the forming optic, whereupon the light absorptive component of the ophthalmic lens absorbs some of the light passing through the ophthalmic lens. The light passing through the ophthalmic lens and the forming optic, which is not absorbed by the light absorptive component of the ophthalmic lens, is used to generate an image having pixel intensity data.

A method of providing correlated depth data in video data, the method comprising identifying depth information encoded within pixel information of a frame of video data, extracting the depth information, and utilizing the depth information for displaying the video data to a user.

Encoded depth data for display

A system to adjust light path length comprising a digital light path length modulator, the digital light path length modulator comprising a polarization modulator to receive polarized light and to modulate a polarization of some or all of the polarized light. The system further comprising an optical path length extender (OPLE) having an entry surface and an exit surface, to direct the light entering the OPLE with a first polarization through the entry surface and along a first light path through the OPLE to exit through the exit surface, and to direct the light entering the OPLE with a second polarization through the entry surface and along a second light path through the OPLE to exit through the exit surface, the second light path through the OPLE having a light path length two or more times longer than the first light path length through the OPLE.
