摘要： An optical combiner for a head-wearable display includes an eyepiece body and a plurality of diffractive optical element (“DOE”) segments. The eyepiece body has an eye-ward side and an external scene side. The DOE segments are disposed within the eyepiece body and are at least partially reflective to image light incident through the eye-ward side of the eyepiece body and at least partially transmissive to external scene light incident through the external scene side of the eyepiece body. The DOE segments are disjoint from each other and each is disposed along a different disjoint surface within the eyepiece body that is oriented at a different angle relative to the other DOE segments. The plurality of DOE segments operate to magnify and reflect the image light incident from an off-axis position to an eyebox sized area.

摘要： Embodiments are described of a light guide including a proximal end, a distal end, a front surface and a back surface, an ambient input region on the front surface near the distal end, and an output region on the back surface near the distal end. A beamsplitter having a plurality of faces has one face optically coupled to the proximal end of the light guide, and a display is optically coupled to another face of the beamsplitter. A projector assembly is optically coupled to a face of the beamsplitter opposite the beamsplitter face that is optically coupled to the light guide. A reflecting element having optical power is positioned at the distal end of the light guide, and a distal optical element is positioned in the light guide near the distal end.

摘要： An adjustable lens includes a first lens member having a first corrugated surface, a second lens member having a second corrugated surface, and blackout regions disposed between the first and second corrugated surfaces. The first corrugated surface includes a periodic structure of alternating ridge and groove sections. The second corrugated surface includes a periodic structure of alternating ridge and groove sections. The blackout regions are positioned to block image light passing through either the ridge sections of the first lens member, or alternatively, the groove sections of the first lens member.

摘要： A camera system includes an image sensor, an aperture, and an adjustable lens. The adjustable lens is disposed in an optical path of the image sensor to focus image light received through the aperture onto a pixel array of the image sensor. The adjustable lens includes first and second lens members and blackout regions. The first lens member includes a first corrugated surface and a first flat surface opposite the first corrugated surface. The first corrugated surface includes a periodic structure of alternating ridge and groove sections. The second lens member includes a second corrugated surface and a second flat surface opposite the second corrugated surface. The second flat surface faces the first flat surface. The blackout regions are disposed between the first and second corrugated surfaces and positioned to block the image light passing through either the ridge or the groove sections of the first lens member.
