Abstract

A scanning ophthalmoscope which produces images of the rear surface of the human eye, and particularly of the retina, by utilising an aspherical mirror to reflect light beams, produced by multiple scanning laser light sources, into the retina. This ophthalmoscope incorporates dynamic systems for the compensation of focus and residual astigmatisms in addition to providing accurate wide field images with adequate resolution and contrast which can be displayed and stored in standard computer systems.
