摘要： 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 a speckle pattern which is produced by light scattered from 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.

摘要： In an ophthalmological measurement method and apparatus, a laser beam of predetermined diameter is projected to the eye fundus and movement of a speckle pattern formed by light scattered by blood cells in blood vessel is detected by a photosensor as fluctuation in speckle light intensity to produce a speckle signal. The speckle light intensity will fluctuate more rapidly with a smaller output from the photosensor when cell velocities are high, while a low cell travel speed will decrease the lowering of the output therefrom. The speckle signal thus mirrors the travel speed of the blood cells in the eye tissues. The differences in the speckle signal are used to identify the blood vessel for automatic tracking of the blood vessel or for measurement of its diameter.

摘要： 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.

摘要： 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.
