An adaptive optics apparatus includes an aberration measuring unit that measures an aberration caused by a test object, the aberration being measured on the basis of returning light that returns from the test object an aberration correcting unit that performs aberration correction in accordance with the aberration measured by the aberration measuring unit an irradiation unit that irradiates the test object with light corrected by the aberration correcting unit and an acquiring unit that acquires information based on a transmittance of the test object on the basis of the aberration measured by the aberration measuring unit.
