Ophthalmic observation apparatus
摘要:
An ophthalmic observation apparatus for observing an object region to be observed of an examinee's eye, comprises: an illumination optical system which has a laser source, a polygon mirror, and a galvano mirror, and which irradiates the object region with a laser beam emitted from the laser source by scanning the laser beam in two dimensions by use of the polygon mirror and the galvano mirror; a photo-receiving optical system which has a beam splitter placed on an optical path between the eye and the polygon mirror, and a photo-receiving element placed in a conjugate position with a pupil of the eye, the photo-receiving element being arranged to receive the laser beam reflected from the object region via the beam splitter, not via the polygon mirror; and an image processing part which processes an output signal from the photo-receiving element in sync with scanning operations of the polygon mirror and the galvano mirror to generate an observation image of the object region.
