Patent: Binocular image alignment for near-eye display

Publication Number: 10178378

Publication Date: 2019-01-08

Applicants: Microsoft

Abstract

A near-eye display device comprises a left-eye optical system and a right-eye optical system. Each of the left-eye optical system and the right-eye optical system comprises a holographic optical component positioned in a field of view of a user eye, an image source configured to emit imaging light, and an alignment optical component, wherein projection beam path between the image source and the light-deflecting optical component and an alignment beam path between the alignment optical component and the light-deflecting component share a common optical path.

Background

A near-eye display device may provide virtual images to a user’s eye to provide an immersive augmented-reality experience. A virtual image may be provided in various ways. In one example, a near-eye display device may include an image source configured to project an image along an optical path via one or more optical components to a user’s eye.

Summary

Examples related to the binocular alignment of near-eye display devices are disclosed. In one example, a near-eye display device comprises a left-eye optical system and a right-eye optical system. Each of the left-eye optical system and the right-eye optical system comprises a light-deflecting optical component positioned in a field of view of a user eye, an image source configured to emit imaging light, and an alignment optical component, wherein a projection beam path between the image source and the light-deflecting optical component and an alignment beam path between the alignment optical component and the light-deflecting component share a common optical path.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
