Abstract
A stereoscopic opthalmoscope for producing a stereoscopic image of an eye fundus, the stereoscopic opthalmoscope including a light source, for emitting a light beam, a light deflector, optically coupled with the light source, for deflecting the light beam into an eye, thereby illuminating the eye fundus of the eye, a relay lens, optically coupled with the eye, for receiving light beams reflected from the eye fundus, thereby producing a relayed three-dimensional image of the fundus, and a stereoscopic imaging apparatus, optically coupled with the relay lens, for stereoscopically acquiring the relayed three-dimensional image. The stereoscopic imaging apparatus includes a dual aperture element, a pixel array image detector and a lenticular lens layer, optically coupled with the pixel array image detector. The lenticular lens layer directs a right view scene of the relayed three dimensional image toward a first plurality of pixels of the pixel array image detector and a left view scene of the relayed three-dimensional image toward a second plurality of pixels of the pixel array image detector.
