Abstract:
1. A fundus observation apparatus comprising: an optical system that splits light from a light source into signal light and reference light, generates interference light by superposing said signal light that has passed through the fundus of an eye and reference light that has passed through a reference optical path, and detects the generated interference light; a scanning part that sequentially irradiates said signal light to a plurality of scanning points by scanning said fundus with said signal light and; an image forming part that forms 1-dimensional images extending depthwise of said fundus at each of said plurality of scanning points based on the detection results of said interference light by said optical system; a detection part that detects the position of said fundus at a prescribed time interval when scanning with said signal light; and a calculation part that calculates the positional misalignment amount for each 1-dimensional image in the fundus surface direction, based on temporal changes of said detected position of said fundus for each 1-dimensional image, wherein the image forming part is configured to form a tomographic image by respectively arranging a plurality of the 1-dimensional images according to an arrangement of the plurality of scanning points.
