Patent ID: 8746884

Claim:
An optical image acquisition apparatus for generating at least an image of an object using return beams returned from the object irradiated by a plurality of measuring beams, said optical imaging apparatus comprising: a single wavefront aberration obtaining unit configured to obtain wavefront aberration in the return beams; and a single wavefront aberration correcting unit configured to correct wavefront aberration in each of the return beams, which enter the wavefront aberration correcting unit with different angles, based on the obtained wavefront aberration, wherein the wavefront aberration obtaining unit is disposed at a position optically conjugate with that of the wavefront aberration correcting unit, and obtains a wavefront aberration in one beam of the plurality of return beams, and wherein the wavefront aberration correcting unit corrects wavefront aberration in each of the return beams based on the obtained wavefront aberration in the one beam.
