In contrast to techniques currently used such as the fundus camera, the strain to which the patient is exposed during the generation of an image of the ocular fundus is reduced by moving a laser beam across the retina in the form of a scanning raster and by directing the light reflected from the retina through a photoelectric receiver to generate a television image. To achieve a very high resolution, the scanning operation provides at least in the interesting image parts signals which are representative of a greater number of image points than correspond...
A method for forming an image of the ocular fundus on a television monitor of television means having a predetermined number of image points corresponding to the applicable television standard, the method comprising the steps of: scanning a laser light beam across the fundus of the eye in the form of a scanning raster; detecting the light reflected from the fundus with a photoelectric receiver; transmitting the output of said receiver to said television means and forming a television image of the fundus; and, during the scanning of the fundus image field...
