Abstract:
A retinal display apparatus for producing a scanned image for viewing by a viewer's eye in response to an image data signal, comprising:a light source for generating light, wherein the light is modulated as a function of the image data signal to define image content;an optical scanner array having a plurality of light reflecting surfaces, the light reflecting surfaces moving at a substantially common frequency with each of the other light reflecting surfaces of the plurality of light reflecting surfaces, wherein light originating from the light source impinges in parallel upon each one light reflecting surface of the plurality of light reflecting surfaces, and wherein light is redirected by each respective one of the plurality of light reflecting surfaces along a corresponding one of a plurality of optical paths; andan eyepiece, positioned along the plurality of optical paths between the eye and the scanner array, receiving the redirected light from each one of the plurality of light reflecting surfaces to form a plurality of respective exit pupils through which the image is scanned, wherein there is a one to one correspondence between each one exit pupil of the plurality of exit pupils and a corresponding one optical path of the plurality of optical paths and a corresponding one light reflecting surface of the plurality of light reflecting surfaces, and wherein for an aligned one or more of the plurality of exit pupils which is aligned with an entrance pupil of the viewer' eye, the image is scanned onto the viewer's eye.
