Abstract
A fundus photographing apparatus includes a wavefront detecting optical system having a wavefront sensor for receiving reflection light from a fundus and measuring wavefront aberration of an eye, a wavefront compensating device for compensating the wavefront aberration, and a deviation detecting part for detecting deviation information corresponding to deviation between an effective region in which aberration compensation by the wavefront compensating device is effective, and a wavefront measuring region in which the wavefront aberration is measured by the wavefront detecting optical system, with respect to a direction perpendicular to an optical axial direction.
