  • Patent number: 9417447
    Abstract: A rod lens array includes a plurality of columnar rod lenses each having a refractive index distribution in which a refractive index continuously decreases from a central axis thereof to an outer periphery, and arranged in at least one row to align the central axes in parallel to each other. Each of the plurality of columnar rod lenses includes an emission-side end portion region, an incident-side end portion region, and an intermediate region between the emission-side end portion region and the incident-side end portion region, each having a central refractive index. The central refractive index of the incident-side end portion is equal to that of the emission-side end portion region in an optical axis direction, and the central refractive index at the intermediate region is higher than those of the emission-side and incident-side end portion regions.

  • Patent number: 9232102
    Abstract: A contact-type image sensor is designed to prevent, in an effective manner, dust from entering into a space between a rod lens array and a light receiving sensor. A rod lens array includes a large number of rod lenses between two flat substrates and between spacers located at left and right ends; one row of the rod lenses is arranged in such a way that central axes of the rod lenses become parallel to each other. At an emission side of a rod lens in an axis line direction, each substrate includes an extension portion, whose length is determined based on an operating distance of the rod lens. A lower end of the extension portion of each substrate is in contact with an upper surface of a sensor substrate. In this manner, the rod lens array is positioned with high accuracy with respect to the light receiving sensor.

  • Patent number: 5090416
    Abstract: An ophthalmological diagnosis method and an apparatus for carrying out the method is disclosed. According to the invention, one of a plurality of laser beams is selected depending upon the tissue layers in the eye fundus to be diagnosed, and is projected thereon. Light is scattered by blood cells within a tissue layer of the eye fundus that depends upon the wavelength of the selected laser beam. The scattered light is received and photoelectrically converted into an electrical signal, which is then evaluated to measure the blood flow state within the tissue layer of the eye fundus.

    Assignee: Kowa Company, Ltd.
    Inventors: Kouji Ogino, Yoshihisa Aizu
  • Patent number: 4952050
    Abstract: Disclosed is an ophthalomological diagnosis method and apparatus in which a blood vessel in the eye fundus is illuminated with a laser beam of a predetermined beam spot whose diameter is substantially equal to or smaller than that of the blood vessel in order to produce diffraction-plane speckles which are formed at a Fourier-transform plane by light scattered from the eye fundus. Boiling motion of the diffraction-plane speckle pattern thus produced is then detected through a multiple detection aperture pattern which is disposed at the Fourier-transform plane and comprised of a plurality of small apertures to obtain a speckle signal which is evaluated to measure velocity of the blood flowing through the blood vessel concerned. This arrangement makes it possible to detect the speckle signal without any effect of averaging the signal with an increase in intensity detected, thus enabling advantageous and successful measurement of the blood flow state in the eye fundus.

Boiling motion of the speckle pattern thus produced is then detected through a multiple detection aperture pattern comprised of a plurality of small apertures as fluctuation in a total amount of light passing through the small apertures to obtain a speckle signal which is evaluated to measure velocity of the blood flowing through the blood vessel concerned. This arrangement makes it possible to detect the speckle signal without any averaging process with an increase in intensity detected, thus enabling advantageous and successful measurement of the blood flow state in the eye fundus.

  • Patent number: 4848897
    Abstract: An ophthalmological diagnosis apparatus is disclosed that has an optical spatial frequency filter, a double diffraction optical system whereby an eye fundus image formed at a first image plane that is conjugate with the eye fundus is again formed at a second image plane, a magnifying optical system for expanding the eye fundus image formed on the second image plane, and a detecting aperture for detecting movement of laser speckles formed at the image plane of magnifying optical system as fluctuations in the intensity of the speckle light. Advantages of the apparatus include the ease with which a single, specific blood vessel can be selected; unnecessary light components can be filtered out, improving the S/N ratio of the speckle light detection; the optical system does not need to be high-precision; good operability; and measurement results that are much more reliable and reproducible.

  • Patent number: 4743107
    Abstract: An ophthalmological diagnosis method and an apparatus for carrying out the method are disclosed. According to the method a region of the eye, e.g. the fundus, is illuminated with a laser beam of prescribed diameter to produce a laser speckle pattern formed by light scattered by blood cells within the tissue of the eye, movement of the laser speckle pattern is detected as fluctuation in the light intensity of the speckles at an observation point and a speckle signal corresponding to the detected movement is produced, the power spectrum distribution of the speckle signal is obtained, the power spectrum distribution configuration is evaluated from the results of a calculation of the mean frequency thereof and the blood flow state in the tissue is determined from the results of the evaluation.
