Patent application numberDescriptionPublished
20080234972OPTICAL IMAGE MEASUREMENT DEVICE AND IMAGE PROCESSING DEVICE - An optical image measurement device is configured to form a tomographic image at each of a plurality of cross sections of a measurement object, and the optical image measurement device comprises: an image processor configured to execute an arithmetic operation based on a tomographic image at one cross section of the plurality of cross sections and another tomographic image at each of one or more cross sections other than the one cross section, thereby forming a new tomographic image at the one cross section.09-25-2008
20080239240OPTICAL IMAGE MEASUREMENT DEVICE - An optical image measurement device has: an interference-light generator configured to generate an interference light by splitting a low-coherence light into a signal light and a reference light and superimposing the signal light having passed through an eye and the reference light having passed through a reference object; a detector configured to detect the generated interference light; and a scanner configured to scan a projection position of the signal light on the eye, and the optical image measurement device is configured to form an image of the eye based on a result of detection by the detector. The optical image measurement device comprises a projector configured to project fixation information for fixing the eye onto a fundus oculi of the eye when the scanner scans with the signal light.10-02-2008
20080259275EYE MOVEMENT MEASURING APPARATUS, EYE MOVEMENT MEASURING METHOD AND RECORDING MEDIUM - An eye movement measuring apparatus comprises: an image forming part configured to obtain data optically to form a fundus oculi image of an eye based on the obtained data; and an image analysis part configured to analyze the formed fundus oculi image to determine eye movement of the eye.10-23-2008
20090153873Optical Image Measuring Apparatus - Provided is an optical image measuring apparatus capable of obtaining a high-accuracy image without being influenced by a movement of an object to be measured. Flash light is emitted from a xenon lamp (06-18-2009
20090190092FUNDUS OCULI OBSERVATION DEVICE AND OPHTHALMIC IMAGE DISPLAY DEVICE - A fundus oculi observation device comprises: a first image forming part configured to form a 2-dimensional image of a surface of a fundus oculi of an eye; a second image forming part configured to form a tomographic image having a cross-sectional position in a measurement region of the fundus oculi corresponding to a partial region of the 07-30-2009
20100142780OPTICAL IMAGE MEASURING DEVICE, OPTICAL IMAGE MEASURING PROGRAM, FUNDUS OBSERVATION DEVICE, AND FUNDUS OBSERVATION PROGRAM - An optical image measuring device which can form a highly reliable image even if an object moves during scanning of a signal light is provided. An optical image forming device 06-10-2010
20100157311OPTICAL IMAGE MEASUREMENT DEVICE - Such an optical image measurement device is provided that is capable of acquiring a clear image even when the intensity of an interference light is low. A fundus oculi observation device 06-24-2010
20100188502Optical image measurement device - A fundus oculi observation device acts as an optical image measurement device capable of measuring an OCT image such as a tomographic image of a fundus oculi, or the like, and is configured so as to calculate the signal level of the formed OCT image, determine whether the signal level exceeds a threshold value, and change the position of a reference mirror so that the signal level is determined to exceed the threshold value.07-29-2010
