A scanning laser ophthalmoscope with a wide field of view provides a color image of an interior portion of a patient's eye at varying depths while the patient is simultaneously presented with a fixation target designed to probe his visual function. The scanning laser ophthalmoscope includes an illumination system, a capturing and detection system and a target image generating system wherein the optical paths of each of these systems is separated by one or more beam splitters to prevent a chief ray from the patient's eye from being blocked so as to eliminate shading off effects in the captured image. A simplified scanning system is employed that includes only one scanner with a moveable reflective surface. A passive, stationary optical element is employed to generate a line of light from a point of light that impinges on the optical element, the line of light being scanned in a direction perpendicular to the line by the single scanner.

[ What is claimed and desired to be secured by letters patent is:] [1.] A scanning laser ophthalmoscope comprising:a source of laser light;a scanning system for generating a two dimensional area of illumination from said laser light;a first beam splitter for reflecting said illumination from said scanning system towards a patient's eye and for passing therethrough light reflected from said patient's eye;an image capturing system for detecting light reflected from said patient's eye and for generating an image of an interior portion of said eye from the detected light;a second beam splitter coaxial with said first beam splitter for receiving light reflected from said patient's eye and passed through said first beam splitter and for reflecting said light to said image capturing system; anda video display for generating a target image, said video display being positioned with respect to said first and second beam splitters such that light from said video display passes through said first and second beam splitter to said patient's eye so that said target image is perceivable by the patient.
