ABSTRACT:
A microscope with a flexible fiber-optic bundle used as a scanner is provided to assist the vision of people; particularly to enable persons with vision defects to read. The eyepiece of the microscope spreads the enlarged images onto the functional portion of the retina of the user. A lenticular screen is used as a diffuser in the microscope. The person moves one end of the fiber-optic bundle along the material to be viewed in order to scan it. The flexibility of the fiber-optic bundle facilitates the scanning motion. The character images are broken up into small segments by the fibers. In each segment the light intensity is substantially the average of the light received by that fiber of the bundle. Thus, confusing background details of the paper, etc., on which the matter is written, are substantially subdued or eliminated.
