  • Publication number: 20150320309
    Abstract: An ophthalmologic apparatus comprises a light source 12, an optical measurement system 13 that radiates first light from the light source to inside an eye to be examined and guides first reflected light from the eye, an optical reference system (24, 22) that radiates second light from the light source to a reference surface and guides second reflected light from the reference surface, a photo detector 26 that detects interfering light between the first reflected light from the optical measurement system and the second reflected light from the optical reference system, and a processor that determines a position of a measuring portion of the inside of the eye based on the detected interfering light. The optical measurement system comprises an incident angle changing member 46 that changes an incident angle of the first light radiated to the eye within a predetermined angular range relative to an axis of vision of the eye.

  • Publication number: 20150255951
    Abstract: A wavelength-swept light source apparatus comprises a light source that emits a wavelength-swept light that varies in a predetermined cycle, a mode hop detector that detects a mode hop of the wavelength-swept light emitted from the light source; and a control unit that controls at least one of a parameter that defines a specified period having a predetermined fixed or variable time length provided in the predetermined cycle and a control parameter of the light source, thereby to set an occurrence timing of the mode hop detected by the mode hop detector outside of the specified period.

  • Publication number: 20150085256
    Abstract: An ophthalmological device emits light from a measurement optical system to an eye to be examined and calculates a dimension along the eye axis of a target portion of the eye from interfering light composed of reflected light from the eye and reference light. The measurement optical system includes incidence position changing member that changes the incidence position of light emitted to the eye, and driving unit that drives the incidence position changing member so as to scan at the incidence position of emitted light in a predetermined region of the eye. The predetermined region is a region where a straight line passes through when the straight line radially extended from the cornea apex of the eye is circumferentially moved over a predetermined angle range in the case of the eye is viewed from the front.

  • Publication number: 20140327918
    Abstract: Provided is an optical tomographic device including a measurement optical system that irradiates light from a light source to inside a subject and guides reflected light therefrom; a reference optical system that guides the light from the light source as reference light; a calibration optical system that irradiates at least one calibration reflecting surface with light from the light source branched from the measurement or reference optical system, and guides the reflected light reflected by the calibration reflecting surface; a light-receiving element that receives the interfering light for measurement formed by synthesizing the reflected light guided by the measurement optical system and the reference light, and the interfering light for calibration formed by synthesizing the reflected light guided by the calibration optical system and the reference light; and an arithmetic logic unit that corrects the received interfering light for measurement by using an analysis result obtained by analyzing the received

  • Patent number: 8702153
    Abstract: Provided is a vehicular door including a load transfer member. The load transfer member includes a transfer member body disposed in a wide-thickness portion in a door body, and a projection projecting downward from the transfer member body. The transfer member body has a lower region whose surface on a door-outer-panel side abuts on, or comes close to, the inner surface of the door outer panel, and an inclined region whose door-outer-panel side surface is inclined to come apart from the door outer panel and whose surface on a door-inner-panel side abuts on, or comes close to, the inner surface of the door inner panel. The thickness of the lower region and the inclined region in a door-thickness direction is set narrower than the width of an insertion portion between the door inner panel and a door beam.

  • Publication number: 20130229627
    Abstract: An ophthalmic apparatus is provided with a light source, an optical measurement system, an optical reference system, an optical calibration system, a light receiving element, and a processor. The light receiving element receives an interference light for measurement produced by both the reflected light guided by the optical measurement system and the reference light guided by the optical reference system, and also receives an interference light for calibration produced by the calibration light guided by the optical calibration system and the reference light guided by the optical reference system. The processor determines a position of a measuring portion inside an eye to be examined by Fourier-analyzing the interference light for measurement and the interference light for calibration.
