Abstract: An ophthalmologic information processing apparatus corrects an image of a subject's eye formed by arranging a plurality of A-scan images acquired by scanning inside the subject's eye with measurement light deflected around a scan center position. The ophthalmologic information processing apparatus includes a specifying unit and a transforming unit. The specifying unit is configured to specify a transformation position along a traveling direction of the measurement light passing through the scan center position, the transformation position corresponding to a pixel position in the image. The transforming unit is configured to transform the pixel position into the transformation position.

Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, first photographing system, first movement mechanism, and controller. The illumination system includes a slit forming unit that forms a slit for generating slit light and projects the slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The first movement mechanism moves a movable portion that includes at least the slit forming unit. The controller performs a first control for the first movement mechanism to move the movable portion and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other.

Abstract: An ophthalmologic information processing apparatus according to the embodiments includes a search unit, a correction unit, and a display control unit. The search unit is configured to search for filter information for correcting an aberration in complex OCT data of a subject's eye so that a quality of the complex OCT data becomes a predetermined level. The correction unit is configured to correct the aberration in the complex OCT data based on the filter information searched by the search unit. The display control unit is configured to display, on a display means, aberration information on a pupil surface of the subject's eye corresponding to the filter information searched by the search unit.

Abstract: The object of the present invention is to develop an ophthalmologic microscope of a new method that increases the degree of freedom in the optical design in the Galilean ophthalmologic microscope provided with an OCT optical system. The present invention provides an ophthalmologic microscope, wherein an observation optical system, an objective lens, and an OCT optical system are placed in such a way that the optical axis of the OCT optical system does not penetrate through objective lens, and the optical axis of the observation optical system and the optical axis of the OCT optical system are non-coaxial, and wherein the ophthalmologic microscope further comprises a SLO optical system that scans a light ray which is a visible ray, a near infrared ray, or an infrared ray and guides the light to the subject's eye so as to become substantially coaxial with the optical axis of the OCT optical system.

Abstract: An embodiment is a method of processing an optical coherence tomography (OCT) image. The method is configured to acquire a plurality of images by applying a plurality of OCT scans corresponding to a plurality of different polarization conditions to a sample, and then generate a mean image with a reduced birefringence-derived artifact by applying averaging to the plurality of images corresponding to the plurality of different polarization conditions.

Abstract: A full-range imaging method doubles imaging range of conventional techniques by removing mirror images of an imaged object that limit conventional images to a “half-range” and that are caused in part by the loss of phase information in a detected signal. Phase information of the detected signal is reconstructed with an averaging technique based on a modulated phase induced in the detected signal during scanning.
