Patent ID: 8801178

Claim:
A fundus photographing apparatus, comprising: a photographing optical system including: a first light source, an optical system for irradiating a fundus with light from the light source, and an optical system for receiving first reflection light from the fundus and photographing a fundus image; a wavefront detecting optical system including: a second light source for irradiating the fundus, and a wavefront sensor for receiving second reflection light from the fundus and measuring wavefront aberration of an eye; a wavefront compensating device disposed on an optical path of the photographing optical system for compensating the wavefront aberration by controlling a wavefront of incident light; and a deviation detecting part for detecting deviation information corresponding to deviation between an effective region and a wavefront measuring region with respect to a direction perpendicular to an optical axial direction, wherein aberration compensation by the wavefront compensating device is effective in the effective region and the wavefront aberration is measurable by the wavefront detecting optical system in the wavefront measuring region.
