Wide Field Specular Scanning Device

US Patent:

4323299, Apr 6, 1982

Filed:

Jul 3, 1980

Appl. No.:

6/165568

Inventors:

Calvin W. Roberts - New York NY

International Classification:

G02B 2106, A61B 312

US Classification:

350 91

Abstract:

The present invention relates to a wide field specular scanning device, especially intended for the examination under magnification of a selected area within the cornea of the eye. The device includes a specular microscope incorporating a converging lens and an objective lens or a group or series of lenses performing the functions thereof. A beam of light from a light source is passed through the lenses of the microscope into the cornea of the subject through a reciprocating or oscillating mask or plate having a first slit to one side of the optical axis of the microscope through which the beam is passed and a second slit to the opposite side of said axis a predetermined distance from the first slit through which the reflected beam transmitted backward through the microscope is passed through a magnifying lens or other device either for direct observation or onto a screen or photo-sensitive surface. By oscillating the mask at a rate which is above the image retention rate of the eye, the observer may derive an accurate impression of a selected area within the cornea of the eye. A particular advantage of the device is that the image is of high contrast and only a minimal quantity of stray light fractions are incorporated in the image.
