20100321700 | OPTICAL COHERENCE TOMOGRAPHIC IMAGING APPARATUS AND OPTICAL COHERENCE TOMOGRAPHIC IMAGING METHOD - A beam diameter varying portion varies a first beam diameter of a measuring beam incident on an optical portion to a second beam diameter larger than the first beam diameter. An adjustment portion adjusts a condensing position of the measuring beam on the optical portion based on intensity information of a return beam from a position of an inspection object with the first beam diameter. The beam diameter is varied from the first to the second beam diameter by the beam diameter varying portion at the position adjusted by the adjustment portion to cause the measuring beam having the second beam diameter to be incident. A condensing position can be adjusted in a relatively short time because the measuring beam small in beam diameter is used, and a combined beam can be acquired with high transverse resolution because the measuring beam large in beam diameter is used. | 12-23-2010 |

The imaging apparatus according to the present invention further includes a beam diameter changing unit for changing a beam diameter of the measuring beam. Furthermore, the imaging apparatus according to the present invention includes a detection unit configured to detect the combined beam at a resolution according to the beam diameter. | 02-03-2011 |
20110199579 | IMAGE CAPTURE APPARATUS AND METHOD - It has been very cumbersome to determine whether or not alignment is required before the fundus image is acquired after the tomographic image is acquired, causing the reduction in diagnostic efficiency. An ophthalmic apparatus is provided to solve this problem, which comprises an irradiation unit that irradiates an eye to be inspected with a first beam for acquiring a tomographic image of the eye and a second beam for acquiring a fundus image of the eye, the second beam having a beam diameter larger than the beam diameter of the first beam; and a determination unit that, based on information indicating a shift amount between an irradiation position of the first beam in the eye and an ocular axis of the eye, determines whether or not the irradiation position of the second beam falls within a range in which the fundus image can be acquired. | 08-18-2011 |
20120062901 | IMAGING DEVICE AND IMAGING METHOD - The present invention relates to a structure in which a sensor includes a first area and a second area upon which dispersed first and second lights are focused. The first and second areas are disposed in a dispersion direction or a direction perpendicular to the dispersion direction. A distance between the first and second areas is adjusted by using a distance between a plurality of fiber ends from which a plurality of combined lights exit and an optical magnification at a detecting section. | 03-15-2012 |
20120092617 | EYEGROUND IMAGING APPARATUS AND CONTROL METHOD THEREFOR - A tomographic-image pickup unit is controlled so as to capture a tomographic image in response to a signal input from a signal input unit. Then, a display unit is controlled so as to display the captured. tomographic image. An eyeground-image pickup unit is controlled so as to capture a two-dimensional image in response to a signal input from the signal input unit while the tomographic image. is displayed on the display unit. Therewith, the user can more easily perform imaging, and the time load on the subject is reduced. | 04-19-2012 |
20120249961 | FUNDUS INSPECTION APPARATUS - In an OCT device, even if an alignment according to a pupil center and a position where a tomographic image can be photographed at a good position may be different according to a subject, automatic alignment is continued at a position where an image quality is good. In a fundus inspection apparatus, an initial adjustment target position on an obtained anterior ocular segment image and an optical axis of a measurement optical system are coincided with each other, and then initial position adjustment is performed. When an instruction for moving an initial adjustment target position is issued, the measurement optical system is moved by a moving amount corresponding to the instruction. At the same time, the initial adjustment target position on the anterior ocular segment image is changed to a position after the movement of the measurement optical system, and positional adjustment is performed again. | 10-04-2012 |
20120253183 | IMAGE PROCESSING APPARATUS, OPHTHALMIC APPARATUS, AND OPHTHALMIC SYSTEM - To reduce confirmation time by an examiner to increase the diagnosis efficiency, a medical system including a medical apparatus that acquires a tomographic image of an object to be examined using combined light generated by combining return light from the object to be examined to which measuring light is emitted and reference light corresponding to the measuring light includes a display control unit configured to control a display unit to sequentially display the tomographic images in the predetermined region on the display unit, and a changing unit configured to change a display time period for the tomographic images displayed in the predetermined region based on the number of the tomographic images to be displayed. | 10-04-2012 |
