Imaging apparatus and method for taking image of eyeground by optical coherence tomography

摘要

An optical unit concentrates light beams from measurement-light paths at first and second irradiation positions on an eyeground. Next, a control unit controls a scanning unit so that the light beams concentrated at the first and second irradiation positions are scanned in first and second scanning areas of the eyeground and so that the first and second scanning areas overlap to form an overlap area. A tomographic-information acquisition unit acquires first tomographic information and second tomographic information in the first and second scanning areas from interference light. Third tomographic information is acquired from the first tomographic information and the second tomographic information in the first and second scanning areas on the basis of the first tomographic information and the second tomographic information in the overlap area.

主权项

1. An imaging apparatus for acquiring plurality of tomographic images of a subject's eye based on a plurality of combined lights formed by combining a plurality of return lights from the subject's eye irradiated with a plurality of measurement lights and a plurality of reference lights corresponding to the plurality of measurement lights, the imaging apparatus comprising:
a scanning unit configured to scan the plurality of measurement lights on scanning areas of an eyeground of the subject's eye, a part of adjacent scanning areas being overlapped with each other; and an acquisition unit configured to acquire an image of the eyeground based on tomographic image information about the eyeground in the scanning areas.
