摘要： According to one embodiment, a data processing method is used for processing collected data acquired with respect to each A-line by swept-source OCT using a wavelength sweeping light source having a predetermined wavelength sweeping range. The data processing method detects a reference signal assigned in advance to a clock, the wavenumber of which linearly varies along the time axis, in a predetermined wavelength position within the predetermined wavelength sweeping range. Then, the data processing method sequentially performs sampling of the collected data based on the clock with reference to the predetermined wavelength position where the reference signal detected is assigned. Further, the data processing method forms an image of a corresponding A-line based on the sampled collected data.

摘要： An illumination system for projecting illumination light onto an eye. A left (right) light receiving system includes a left (right) objective lens and left (right) image sensor, and guides returning light of the illumination light to the left (right) image sensor via the left (right) objective lens. The objective optical axes of the left and right light receiving systems are disposed nonparallelly to each other. A projection system includes a projection system objective lens, and projects light onto the eye via the projection system objective lens. An optical scanner is used for scanning the eye with the light from the projection system. A deflection member is disposed near the objective optical axes, disposed in the optical path of the projection system between the optical scanner and the projection system objective lens, and deflects the optical path.

摘要： An illumination system of an ophthalmologic microscope system projects illumination light onto a patient's eye. A light receiving system guides returning light of the illumination light to an image sensor. A display controller controls a display device to display an image obtained by the image sensor. A magnification changing unit changes display magnification of the image. An interference optical system detects interference light generated from returning light of measurement light from the eye and reference light. An optical scanner is used to scan the eye with the measurement light. An OCT data generation unit processes a detection result of the interference light to generate data. A condition setting unit sets a projection condition of the measurement light in accordance with change in the display magnification. An OCT controller controls the interference optical system and/or the optical scanner based on the projection condition.

摘要： Methods and systems for angiographic imaging with optical coherence tomography (OCT) are described using ratio-based and angiographic deviation based calculations. In using these calculations to determine motion, arbitrary interframe permutations may be used, post-calculated, non-linear results for projection visualization may be averaged, poor matches may be eliminated on an A-line by A-line basis, windowing functions may be used to improve results, partial spectrums may be used when capturing data, and a minimum intensity threshold may be used for determining which pixels to use.

摘要： An ophthalmologic apparatus which is capable of preferably executing position matching between an eye and optical system is provided. An ophthalmologic apparatus of an embodiment includes an examination optical system, supporting part, driver, two or more imaging parts, analyzer and controller. The examination optical system is used for an examination of the eye. The supporting part supports a face of a subject. The driver moves the examination optical system and the supporting part relatively and three-dimensionally. The two or more imaging parts substantially simultaneously photograph an anterior eye part of the eye from different directions. The analyzer obtains a three-dimensional position of the eye by analyzing two or more photograph images acquired by the two or more imaging parts substantially simultaneously. The controller controls the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part.

摘要： A processing for specifying a correspondence relationship of feature points between two sets of optical data can be highly precise and efficiently carried out. The correspondence relationship of the perpendicular edges is obtained based on the assumption that the object is a building, in the processing for integrating the three-dimensional model obtained from the point cloud position data and the three-dimensional model obtained from the stereophotographic image. In this case, one perpendicular edge is defined by the relative position relationship with the other perpendicular edge, and the correspondence relationship is high-precisely and rapidly searched.
