Google patents glasses that adjust image focus to counter lens distortion
Google has been granted a patent for a head-worn display that uses a specific optical path to show extended reality images. The system applies two different levels of optical power to the light, with the first step specifically designed to cancel out the distortion caused by a protective layer between the user and the display.
In the filing’s own words
A head-worn display (HWD) is configured to present an extended reality (XR) image to a user at a predetermined finite distance. To this end, the HWD includes an optical path having a first component configured to apply a first optical power to light representing the XR image emitted from a light engine. Further, the optical path includes a second component, different from the first component, configured to apply a second optical power to the light having the first optical power applied. Additionally, the optical path is configured to present the light having the first and second optical powers applied to the user such that the XP image is presented to the user at a finite distances based on the first and second optical powers.
What exactly they claim (claim 1)
1. An optical path for a wearable display, the optical path including: a light engine configured to emit light representing an image such that the light representing the image has a first optical power applied; a lightguide including: an element configured to apply a second optical power to the light representing the image with the first optical power applied; and an outcoupler configured to direct the light representing the image with the first and second optical powers applied such that the image is presented to a user of the wearable display at a finite distance from the wearable display based on the first optical power and the second optical power; and a protective layer disposed between the lightguide and the user, wherein the light engine is configured to apply the first optical power to the light representing the image so as to mitigate at least a portion of a third optical power applied by the protective layer to the light representing the image.
