US 2014/0111769 A1 · Compensation Optical Apparatus and Image Sensing Apparatus

Abstract

A compensation optical apparatus for obtaining and image of an object without reduction in image quality irrespective of aberration compensation, includes: a division unit for dividing a return beam from a measured object; an aberration measurement unit for measuring an aberration caused by the measured object, with a divided beam from the division unit; an aberration compensation unit for performing aberration compensation based on the aberration measured by the aberration measurement unit; a projection unit for projecting a beam obtained by the aberration compensation in the aberration compensation unit to the measured object; an acquirement unit for acquiring a value exhibiting a state of the measured object based on the return beam from the measured object, which is obtained by the beam projected from the projection unit; and a control unit for retreating the division unit from an optical path based on the value acquired by the acquirement unit.

Dependent claims

An ophthalmologic apparatus comprising:

a division unit capable of being inserted in an optical path or being retreated from the optical path and for dividing, in a case where the division unit is inserted in the optical path, a return beam from an eye to be inspected irradiated by a measuring beam to a first beam and a second beam;
an aberration measurement unit for measuring, based on the first beam, an aberration of at least one of the measuring beam and the return beam;
an aberration compensation unit for compensating, based on the measured aberration, the aberration of at least one of the measuring beam and the return beam;
and
an image acquirement unit for acquiring an image of the eye to be inspected, based on the second beam in a case where the division unit is inserted in the optical path, and for acquiring an image of the eye to be inspected based on the return beam in a case where the division unit is retreated from the optical path.
