|20130308100||COLOR CODED TOPGRAPHER AND METHOD OF DETERMINING A MATHEMATICAL MODEL OF A CORNEAL SURFACE - A corneal topographer is described, the topographer comprising: —a multi-colored stimulator comprising a plurality of light sources arranged to form a multicolored pattern of source points for projecting a plurality of light rays onto a surface of an object of interest, such as a cornea; —a lens-camera system arranged to receiving a respective plurality of reflected light rays reflected of the surface of the object of interest, thereby forming a pattern of image points; —a computational unit for determining a mathematical model of the surface; the computation unit comprising a memory unit provided with color pattern information based on the multicolored pattern of source points of the stimulator; the computational unit being arranged to, for each of the plurality of reflected light rays, establishing a one-to-one correspondence between a source point and an image point based on the color pattern information; the computational unit further being arranged to construct, based on positions of the image points and positions of the corresponding source points, the mathematical model of the surface.||11-21-2013|
|20130176535||CONFOCAL LINE-SCANNING OPHTHALMOSCOPE - 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.||07-11-2013|
|20110105943||Apparatus For Corneal Shape Analysis And Method For Determining A Corneal Thickness - A method of determining a corneal thickness and an apparatus for determining said is provided. The method comprises the following the steps:—illuminating a cornea by a plurality of stimulator point light sources, capturing an image of the cornea comprising reflected images of the stimulator point light sources, obtaining a model representing an anterior surface of the cornea,—constructing a second model representing a posterior surface of the cornea from the image by ray-tracing the reflected images of the stimulator point light sources towards the model representing the anterior surface of the cornea, determining the corneal thickness from the model representing the anterior surface and the second model representing the posterior surface.||05-05-2011|
|20110037845||OPHTHALMIC APPARATUS AND METHOD FOR INCREASING THE RESOLUTION OF ALIASED OPHTHALMIC IMAGES - 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.||02-17-2011|
|20090009715||Confocal Color Ophthalmoscope - A confocal color opthalmoscope having a line-shaped, incoherent light source. The light emitted from the linear light source is focused and scanned to illuminate a region of a retina of an eye with a line oriented perpendicular to the direction of scan. Light reflected from the retina of eye is collected, descanned and focused onto a line shaped detector. A dispersive element may be used to illuminate a multi-slit plate with different spectral components. The retina may then be scanned with multiple slits, each having a different spectral makeup. Light reflected from the retina may be descanned and imaged back to a multiple linear array photo-detector. One of said slits may be illuminated with infra-red radiation, and the others with visible light. A filter may allow only the infra-red light to reach the retina during an initial alignment mode, allowing non-mydriatic alignment of the opthalmoscope.||01-08-2009|
