Ophthalmic apparatus and method of controlling same

An ophthalmic apparatus, comprising:

• a light source;
• an illumination optical system configured to generate slit-shaped illumination light using light from the light source;
• an optical scanner configured to deflect the illumination light to guide the illumination light to a fundus of a subject's eye;
• an imaging optical system configured to guide returning light of the illumination light from the fundus to an image sensor;
• and
• a controller configured to control the image sensor using a rolling shutter method so as to acquire light receiving result of the returning light corresponding to an irradiated position of the illumination light on the fundus, wherein
• the illumination optical system includes:
• a slit with a slit-shaped aperture capable of being arranged at a position substantially conjugate optically to the fundus;
• an iris aperture arranged between the light source and the slit, and configured to be capable of being arranged at a position substantially conjugate optically to an iris of the subject's eye;
• and
• an optical element arranged between the light source and the iris aperture, and configured to deflect the light from the light source.
