Eye-tracking fundus imaging system

A head mounted display (HMD), comprising:

• a display layer configured to emit a display light for presentation to a user;
• an array of light sources disposed on the display layer and configured to be selectively enabled to emit non-visible light to illuminate a fundus of an eye of the user;
• a first optical combiner disposed between the array of light sources and an eyeward side of the HMD, wherein the first optical combiner is configured to:
• receive reflected non-visible light that is reflected by the eye,
• direct a first component of the reflected non-visible light to a first camera to generate an image of the eye, and
• pass a second component of the reflected non-visible light;
• and
• a second optical combiner disposed between the array of light sources and the first optical combiner, wherein the second optical combiner is configured to:
• receive a fundus imaging light responsive to the second component of the reflected non-visible light, and
• direct the fundus imaging light to a second camera to generate an image of the fundus.

A fundus imaging system, comprising:

• a first camera configured to generate at least one image of an eye;
• a second camera configured to generate at least one image of a fundus of the eye;
• an array of light sources configured to be selectively enabled to emit non-visible light to illuminate a fundus of an eye;
• a first optical combiner disposed between the array of light sources and an eyeward side of the fundus imaging system, wherein the first optical combiner is configured to:
• receive reflected non-visible light that is reflected by the eye,
• direct a first component of the reflected non-visible light to the first camera to generate the at least one image of the eye, and
• pass a second component of the reflected non-visible light;
• and
• a second optical combiner disposed between the array of light sources and the first optical combiner, wherein the second optical combiner is configured to:
• receive a fundus imaging light responsive to the second component of the reflected non-visible light, and
• direct the fundus imaging light to the second camera to generate the at least one image of the fundus.
