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.

Abstract: A mobile body is controlled even in a place in which a navigation signal is difficult to receive from a navigation satellite. A three-dimensional information processing unit operates a device or a functional part which measures three-dimensional coordinates of a controlled target and operates a laser scanner or a laser scanning part which obtains three-dimensional point cloud data of the target. The unit includes a positioning section that operates the device or the functional part which measures the three-dimensional coordinates, to calculate the three-dimensional coordinates, and includes a scan controlling section that obtains the three-dimensional point cloud data from the laser scanner or the laser scanning part. The unit also includes a range calculator that calculates a movable range of the target from the three-dimensional coordinates and the three-dimensional point cloud data, and includes a controlled target position calculator that calculates a position of the target in the movable range.
