An apparatus and method are described which provide a unique way of creating a very high resolution image of the retina inside an eye. In one aspect, the apparatus uses a very resolution linear CCD array coupled with structured light projectors (or low power eye safe lasers) to illuminate the retina to capture a very high resolution image segment of the retina. In another aspect, a moving light pattern is used which is tracked by an observer whose eye is being scanned, and the image segments of the retina as the eye tracks the moving light pattern is integrated to form a very high resolution image segment of the retina. In yet another aspect, the structured light projectors can be used to project a known pattern on the retina to reconstruct a 3D map of the retinal surface integrating 3D information computed as the eye tracks a moving light. In yet another aspect, innovative methods are used to register the orientation of the eye being scanned with the very high resolution image segment captured at any point of time.
