  • Patent number: 9572490
    Abstract: The present invention relates to a method for measuring ocular scattering, comprising the steps of: sequentially projecting images from an extensive light source, corresponding to different visual angles, onto the retina; recording the output light in a camera or detector once it has passed through the eye twice; calculating the intensity at the center of each recorded image; calculating the PSF for each angle from the previous intensities; and calculating the average of the value of the PSF between the angles. The invention also relates to a system for carrying out said method. The invention can be used to measure the intensity of the scattered light in an objective manner.

  • Patent number: 8282211
    Abstract: The present invention provides a method and device to image the fundus of the eye using polarized light which includes circular polarization. The invention is most broadly comprised of a device to generate polarization states of light, including circularly polarized light (i.e. potentially combinations of elliptically polarized light and depolarized light combined, elliptically polarized light alone, or circularly polarized light with depolarized light or circularly polarized light alone). This light can be used with any fundus imaging device including but not limited to fundus cameras, scanning laser ophthalmoscopes, confocal scanning laser ophthalmoscopes, optical coherence tomography instruments, with or without some form of wavefront correction. This is a change from common fundus imaging systems which use randomly polarized light or linearly polarized light.

  • Patent number: 6927888
    Abstract: The present invention provides a method and apparatus for improving the signal to noise ratio, the contrast and the resolution in images recorded using an optical imaging system which produces a spatially resolved image. The method is based on the incorporation of a polarimeter into the setup and polarization calculations to produce better images. After calculating the spatially resolved Mueller matrix of a sample, images for incident light with different states of polarization were reconstructed. In a shorter method, only a polarization generator is used and the first row of the Mueller matrix is calculated. In each method, both the best and the worst images were computed. In both reflection and transmission microscope and Macroscope and ophthalmoscope modes, the best images are better than any of the original images recorded. In contrast, the worst images are poorer. This technique is useful in different fields such as confocal microscopy, Macroscopy and retinal imaging.
