Abstract: A line-scanning ophthalmoscope includes a light source to provide a light beam to an object of interest, a beam separating device to receive the light beam, provide the light beam to a scanning device and substantially separate the light beam and the returning light beam from the object of interest, a scanning device to direct the light beam to the object of interest for scanning the object of interest; to receive the light beam returning from the object of interest; and to direct at least part of the reflected light beam towards a detector; and a further scanning device to convert the light beam to a line-shaped light beam.
Abstract: A method for producing an image with an increased resolution from a plurality of aliased ophthalmic images having an original resolution is described. The method comprises the steps of—providing an imaging system capable of acquiring said aliased ophthalmic images,—acquiring said aliased ophthalmic images by the imaging system, thereby generating non-integer pixel displacements between said images by using voluntary or involuntary eye movements,—determining the displacements between said images, and—producing an image with an increased resolution in an overlapping area of said aliased ophthalmic images compared to the original resolution of said images, based on said images and said displacements, using a super-resolution algorithm.
