Method and apparatus to project image on retina at various focal depths utilizing flexible substrate containing optical array

Abstract

The current invention relates to the method to achieve artificial vision with using flexible substrate based light emitting arrays, or optical passage arrays, to project image upon the retina of a human eye. Further, it relates to the method to detect the real-time focal length change of the eye-lens and modify the flexible substrate curvature and distance from the eye to vary global angle configurations of light beams that go into the eye to produce images on the retina at various focus depth of the eye to achieve re-focusable artificial vision.

AI Technical Summary

Benefits of technology

[0013]This method provides the viewer the ability to view the objects of interest in focus at will, while not requiring the viewer's effort to actively participate to achieve such re-focus task.

[0014]This invention helps achieve 3D vision that most closely simulates real-life viewing experience, and can give the impression of viewing a real-life scene where viewer can focus on objects of interest with pure intention.

Problems solved by technology

A fundamental drawback of all existing stereo-vision techniques and 3D movie techniques in the attempt to simulate real-life viewing experience is that when the object images are captured from two different viewing angles, objects 391 and 392 that are focused upon will show up as focused objects when projected on screen.

The existing prior art techniques do not allow viewer to view all objects within same scene clearly and does not have a method to bring objects into focus at viewer's own discretion.

This limitation makes 3D vision of prior art an obvious deviation from reality.

Prior art is limited in the ability to re-produce the life-like stereo-vision viewing experience.
