Abstract
An anisoplanatic aberration correction method and apparatus for adaptive optical biaxial scanning imaging are provided. Insofar as no adaptive optical wavefront sensor and wavefront corrector are added, an anisoplanatic aberration of biaxial scanning is divided into a plurality of isoplanatic sub-fields of view by means of a time-sharing method and according to a beam scanning trajectory; aberration measurement and closed-loop correction are respectively completed in each isoplanatic region sub-field of view, and a residual aberration of a formed image of each isoplanatic region sub-field of view is also supplementally corrected on the basis of an image processing technology, thereby realizing complete correction of an anisoplanatic aberration of a wide field of view. The aberration correction of a wide field of view can be completed only by a single wavefront sensor and a single wavefront corrector, so that the limitation of an isoplanatic region to an adaptive optical imaging field of view can be broken through, the aberration correction and high-resolution imaging of a wide field of view of a retina are realized, almost none of the system complexities is increased, and the method and the apparatus have extremely high practicability. The correction of an image subjected to deconvolution is low in cost, and the correction effect is good.
