Methods and systems for performing optical coherence tomography
First Claim
Patent Images
1. A wearable augmented reality device comprising:
- a light source configured to generate image light;
a stack of waveguides configured to pass light from the world into an eye of a wearer wearing the augmented reality device, wherein each of the waveguides is configured to present augmented reality content to the wearer by directing the image light to the eye,wherein each of the waveguides is configured to guide the image light therein by total internal reflection between opposing surfaces of the waveguide, and wherein one or more waveguides of the plurality of waveguides are configured to output image light to the eye with a different amount of wavefront divergence than one or more other waveguides of the plurality of waveguides; and
an optical coherence tomography system configured to image the eye based on projecting light generated by the light source, via the one or more waveguides, to the eye.

Abstract
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user'"'"'s body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
