Abstract

Improved scanning ophthalmoscopes for scanning the retina of an eye are discussed in the present disclosure. One example scanning ophthalmoscope includes an uncollimated light source, a first scanning element, a second scanning element, a slit of a first aspherical mirror, and a second aspherical mirror. The uncollimated light source produces a beam of light to illuminate the retina. The beam of light is relayed from the first scanning element onto the second scanning element by the slit of the first aspherical mirror. The second aspherical mirror relays the beam of light from the second scanning element to the pupil of the eye.
