Abstract: According to one embodiment, a fundus imaging apparatus includes a light source, an optical scanner, an optical fiber, a light guide system, a photodetector unit, and an image forming unit. The optical scanner scans the fundus of a subject's eye with light from the light source. The optical fiber includes a plurality of optical waveguides. The light guide system guides the light returning from the fundus to the entrance end of the optical fiber. The photodetector unit detects light output from each of at least three regions at the exit end of the optical fiber. The image forming unit forms a first image based on a detection result of light output from a first region of the at least three regions, and a second image based on detection results of light output from two or more regions of the at least three regions other than the first region.

Abstract: An ophthalmologic apparatus is disclosed. In one aspect, the apparatus includes an ocular fundus photographing systems for forming an ocular fundus image of the examined eye, based on a reflective beam from the ocular fundus of the examined eye, and an ocular fundus tracking controller for detecting a gaze direction of the examined eye by receiving the reflective beam reflected at a reflective region of an illumination region illuminated on the ocular fundus and for tracking the ocular fundus based on the detection results of the gaze direction. The ocular fundus tracking controller may include scanning mirrors for scanning an area to detect a reflective beam from the ocular fundus, tracking mirrors for controlling tracking to the ocular fundus, an objective lens disposed opposite to the examined, and an offset mirror M19 for adjusting a detection axis in a gaze direction.

Abstract: A single light emitted from a laser source is split into multiple beams. The multiple beams are illuminated by a multi-beam scanner to scan a substrate of interest. An optical system is provided for focusing the multiple beams independently on the substrate and directing a reflected light or a transmitted light of the multiple beams on the substrate. Aperture regulating members are disposed at equal intervals corresponding to the interval between the multiple beams for controlling the multiple beams directed from the substrate by the optical system. The multiple beams passed through their respective aperture regulating members are received by an optical detector assembly which detect a change in the amount of the multiple beams. The substrate is continuously moved by a movable table on a plane substantially vertical to the multiple beams and in a direction arranged at substantially a right angle to the scanning direction of the multiple beams.
