Optical coherence tomographic imaging apparatus and optical coherence tomographic imaging method

An imaging method comprising:

• varying a condition of a measuring beam that irradiates a retina of a subject eye via a scanning unit, wherein the scanning unit scans the measuring beam on the retina with a vicinity of a cornea of the subject eye as a pivot;
• and
• controlling performance of said varying to vary the condition between a first condition, in which a radially center part of the measuring beam is not blocked, and a second condition, in which the radially center part of the measuring beam is blocked.

An ophthalmologic method in which a tomographic image of a subject eye is acquired based on a return beam of a measuring beam, which is reflected or scattered by the subject eye irradiated with the measuring beam via a scanning unit, and a reference beam corresponding to the measuring beam, wherein the scanning unit scans the measuring beam on the subject eye, said ophthalmologic method comprising:

• varying, by a varying unit, an intensity of the measuring beam and a condition of the measuring beam;
• and
• controlling the varying unit to vary the condition between a first condition, in which a radially center part of the measuring beam is not blocked, and a second condition, in which the radially center part of the measuring beam is blocked, and to adjust an intensity of the measuring beam on the subject eye to a predetermined intensity.
