Abstract: 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 is then processed to derive therefrom its center of gravity, which is taken as a center of a blood vessel to identify the blood vessel. This enables the blood vessel parts to be identified with high accuracy and to be tracked automatically.

Abstract: An apparatus for detecting ophthalmic diseases in a patient's eye includes light projection system for projecting a laser beam at a spot in the eye. The light scattered from the eye is photoelectrically detected and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection. A monitor is provided in the light projection system for monitoring light scattered from the cornea of the eye on which the laser beam is projected, and for monitoring a virtual image which is formed by the cornea surface from light scattered at the exit window of the light projection system to correctly position and align the apparatus in order to ensure accurate protein concentration measurements.

Abstract: An apparatus for detecting ophthalmic diseases, such as inflammation in a patient's eye, includes a projection system for projecting and focusing a laser beam at a selected spot in the eye. The laser light scattered from the eye is photoelectrically detected through a slit in a mask and converted into an electrical signal which is used to determine the protein concentration in the patient's eye. A light shield member is displaceable in front of the mask slit to selectively block diffused light from the eye or scattered laser light to improve the S/N ratio of the electrical signal.

Abstract: A three-dimensional shape measurement apparatus uses a laser beam to illuminate an object. The light reflected from the object is processed to obtain information about the shape of the object in three dimensions. As the beam moves over contour features of the object, there is a corresponding displacement of the focal point of the light reflected back from the object which is calculated to convert it to depth-wise shape information. The apparatus includes a laser light source; deflectors for scanning the laser beam at a set frequency; an optical system for projecting the laser beam scanned by the optical deflectors at the object; detection slits arranged parallel to the direction in which the reflected light is scanned and facing the object along on an optical axis that is perpendicular to the direction of the scanning by the optical deflectors, the slits being placed a certain distance from a point that is optionally conjugate with the object; photosensors for detecting light passing through the detection slits; and a signal processor to eliminate the effect of the reflection characteristics of the object.

Abstract: An ophthalmic measuring method and apparatus according to the present invention are provided for the purpose of measuring the state of microparticles in the aqueous chamber of an eye to be examined which is irradiated with a laser beam to detect the scattering characteristics in the aqueous chamber of the eye. A laser beam with a predetermined wavelength is projected into the aqueous chamber of the eye. Light scattered from the aqueous chamber is received with or without a linear polarizer and evaluated in terms of the changes between the scattering characteristics with or without the linear polarizer in order to measure the number or concentration of the microparticles present in the aqueous chamber for the purpose of detecting ophthalmic diseases.

Abstract: Disclosed is a laser beam scanning system having a laser source for producing a plurality of laser beams each having a different wavelength which are deflected by an acousto-optical deflector to scan an object in at least one direction to produce a video signal representative of the object color image. Because of color dispersion inherent to the acousto-optical deflector, the angle of deflection is dependent on the wavelength of the laser beams. To compensate for the color dispersion, a signal processor is provided to process the video signals derived from the scanning of the object in such a manner that the video signals are processed differently in terms of scanning time one from the other and are output using the same timing.

Abstract: Disclosed is a laser beam scanning system which includes a plurality of laser sources each of which produces a laser beam having a different wavelength. The laser beam component is intensity-modulated with a corresponding color video signal and deflected by an acousto-optical deflector to scan a medium in at least one direction to produce a color image thereon. Because of the color dispersion inherent to the deflector, the angle of deflection is dependent on the wavelength of the laser beam component. To compensate for the color dispersion, a signal processor is provided to adjust the intensity modulation for the corresponding laser beam component in such a manner that each of the laser beam components is intensity-modulated differently from the others in terms of scanning time to obtain substantially the same angle of deflection for all the beam components.
