  • Methods and apparatus for cataract detection and measurement
    Patent number: 8746885
    Abstract: In exemplary implementations of this invention, cataracts in the human eye are assessed and mapped by measuring the perceptual impact of forward scattering on the foveal region. The same method can be used to measure scattering/blocking media inside lenses of a camera. Close-range anisotropic displays create collimated beams of light to scan through sub-apertures, scattering light as it strikes a cataract. User feedback is accepted and analyzed, to generate maps for opacity, attenuation, contrast and sub-aperture point-spread functions (PSFs). Optionally, the PSF data is used to reconstruct the individual's cataract-affected view.
