摘要:
PROBLEM TO BE SOLVED: To provide an ocular fundus imaging apparatus capable of projecting illumination light accurately to a pupil.SOLUTION: The ocular fundus imaging apparatus comprises: a concave mirror system (concave mirrors 31, 35) reflecting illumination light projected from a light source 1 to guide the reflection to a subject eye E, the concave mirror system being disposed in an optical path common between a first illumination optical system 100a illuminating the subject eye E with the illumination light from the light source 1 and a first imaging optical system 100b having a light receiving element 56 receiving the reflection of the illumination light projected to the fundus of the subject eye by the first illumination optical system 100a to obtain a fundus image; an X galvanometer mirror 400a disposed in a position conjugated with the pupil of the subject eye E with respect to a sagittal plane of the concave mirror system, and deflecting the illumination light from the light source 1 in a direction along the sagittal plane of the concave mirror system; and a Y galvanometer mirror 400b disposed in a position conjugated with the pupil of the subject eye E with respect to a meridional plane of the concave mirror system, and further deflecting the illumination light through the X galvanometer mirror 400a in a direction along the meridian plane of the concave mirror system to guide the deflected light to the concave mirror system.SELECTED DRAWING: Figure 3
