  • Publication number: 20030071969
    Abstract: An improved ophthalmic instrument for in-vivo examination of a human eye including a wavefront sensor that estimates aberrations in reflections of the light formed as an image on the retina of the human eye and a phase compensator that spatially modulates the phase of incident light to compensate for the aberrations estimated by the wavefront sensor Optical elements create an image of a fixation target at the phase compensator, which produces a compensated image of the fixation target that compensates for aberrations estimated by the wavefront sensor. The compensated image of the fixation target produced by the phase compensator is recreated at the human eye to thereby provide the human eye with a view of compensation of the aberrations the human eye as estimated by the wavefront sensor. The phase compensator preferably comprises a variable focus lens that compensates for focusing errors and a deformable mirror that compensates for higher order aberrations.

  • Publication number: 20030071124
    Abstract: Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

  • Publication number: 20030053031
    Abstract: An improved ophthalmic instrument including an extended source producing light that is formed as an image on the retina of the human eye and reflected there from to produce retinal reflections derived from the extended source, and a wavefront sensor that estimates aberrations in the retinal reflections. The wavefront sensor includes a plurality of subapertures that form a plurality of images of the extended source from the retinal reflections, an imaging device that captures the plurality of images and outputs image data representing the images, and an image processing computer that generates an estimate of the gradient field of the retinal reflections by applying image correlation techniques in the digital domain to the image data.

  • Publication number: 20030053029
    Abstract: An improved ophthalmic instrument including a wavefront sensor that estimates aberrations in reflections of the light formed as a spot image on the retina of the human eye. The wavefront sensor includes a beam splitter operably disposed between a lenslet array and multiple imaging devices. The lenslet array forms a first array of spots, and the multiple imaging devices capture multiple images of the first array of spots for use in estimating the aberrations of the eye in a manner that minimizes the adverse effects of eye movement on the accuracy of such estimates. The beam splitter preferably comprises a prismatic beam splitter that splits light incident thereto into multiple arms. The multiple image devices may capture at least a first image of the first array of spots at best focus and a second image of the first array of spots near best focus for use in dynamically identifying sub-arrays (pixel areas) of the Hartmann spot imaging device (e.g.

  • Publication number: 20030053028
    Abstract: An improved ophthalmic instrument including a wavefront sensor that estimates aberrations in reflections of the light formed as a spot image on the retina of the human eye, wherein the wavefront sensor includes at least one subaperture that spatially samples incident light; at least one optical element that focuses each sample to a spot; and an image sensor and image processor for measuring location of the spot. The image sensor captures image data of an pixel subaperture defined around the spot and provides the image data to the image processor. The image processor analyzes the image data to identify a subarray of pixels around a peak in the pixel subaperture, fits a predetermined function to the image data for the subarray of pixels, and derives an estimate for spot location based upon location of the fit of the predetermined function.
