Fundus imaging apparatus
A fundus imaging apparatus comprises: a beam emitter (1) which simultaneously emits a first laser beam and a second laser beam having a different wavelength from the first beam; an irradiation optical system (2-10) having a beam scanner (7, 9) which scans the emitted first and second beams in two di...

| description | A fundus imaging apparatus comprises: a beam emitter (1) which simultaneously emits a first laser beam and a second laser beam having a different wavelength from the first beam; an irradiation optical system (2-10) having a beam scanner (7, 9) which scans the emitted first and second beams in two dimensions on a fundus, the irradiation optical system being adapted to irradiate the emitted first and second beams onto the fundus; a first filter (24) which intercepts the first and second beams reflected by the fundus and second fluorescence from the fundus by irradiation of the second beam and transmits first fluorescence from the fundus by irradiation of the first beam; a second filter (25) which intercepts the first and second beams reflected by the fundus and the first fluorescence from the fundus and transmits the second fluorescence from the fundus; an imaging optical system (11-14) having a photo-receiving element (14) which receives the first fluorescence having passed through the first filter and the second fluorescence having passed through the second filter; a filter changer (20a, 21, 21a) which continuously alternately disposes the first filter and the second filter in an optical path of the imaging optical system in sync with scanning by the beam scanner; and image processing means (33) for obtaining a first fundus image based on a received light signal of the first fluorescence from the photo-receiving element and obtains a second fundus image based on a received light signal of the second fluorescence from the photo-receiving element. |
