摘要： In an OCT apparatus used in ophthalmology, if a working distance between an eye to be inspected and an objective lens varies, a shape of an obtained tomographic image is changed. This means that the OCT apparatus cannot be used for examining a variation of eyeball shapes. Provided is an optical coherence tomographic imaging method, including: acquiring a first distance between the eye to be inspected and the objective lens, corresponding to first tomographic image of the eye to be inspected; and correcting the first tomographic image to be second tomographic image corresponding to a second distance between the eye to be inspected and the objective lens, which is different from the first distance.

摘要： To provide a technique preferable for ophthalmic image taking having an image taking optical system for imaging an image on an image sensing element at different imaging magnifications.
The following are included:

an image sensing element (17a) for converting the eye-to-be-examined fundus image (Er) into digital image data;
an image taking optical system for imaging the eye-to-be-examined fundus image (Er) on the image sensing element (17a) at different image magnifications;
fungus illumination means (5) for illuminating fungus at a light intensity interlocking with the imaging magnifications; and
region selection means (33) for selecting a specific region (17c) including a fundus image from the image data in accordance with the imaging magnifications. Moreover, it is characterized to lower the light intensity of the fundus illumination means (5) by interlocking with reduction of the imaging magnifications and contract the specific region (17c) by interlocking with reduction of the imaging magnifications.

摘要： There is provided an ophthalmologic apparatus that prevents ghost light from generating. In the ophthalmologic apparatus, on an optical path commonly used for an eye fundus illumination optical system (1,3,5,6,7,10) and an image taking optical system (10,11,12,14) including an image taking diaphragm (10), an objective lens (2) for forming an image of the image taking diaphragm (10) onto an anterior ocular segment (Er) of an eye (E) to be examined is provided. The objective lens (2) is formed such that the entire light beam (R2) from the center of the image taking diaphragm (10) is substantially perpendicularly incident thereon. The objective lens (3) is a refractive index distributed lens in which a refractive index is high in a vicinity of an optical axis and reduces as a distance from the optical axis increases.
