  • Scanning laser ophthalmoscope
    Patent number: 6099127
    Abstract: An ophthalmoscope is disclosed comprising mirrors to generate a raster scan of laser light, and detect reflections of such light from the fundus of a patient's eye. The laser light originates from sources of at least three distinct wavelengths and is mixed to provide a single beam that, for each resolvable picture element of the raster scan, assumes in sequence each of the wavelengths. The reflected light is used to generate a multi-colored image of the fundus.
