- 摘要:
PROBLEM TO BE SOLVED: To provide a fundus imaging apparatus capable of obtaining a fundus image useful in diagnosis of a fundus of an examinees eye.
SOLUTION: The fundus imaging apparatus comprises: an irradiation optical system including an optical member for focusing a laser beam on the observation surface of the fundus and a scanning means for two-dimensionally scanning the laser beam on the fundus an imaging optical system which shares at least part of the irradiation optical system for obtaining an imaged image by focusing the reflection light of the laser beam reflected from the fundus and receiving the reflection light by a photo-receiving element first beam restriction means placed in a conjugate position with a focus point of the laser beam on the observation surface of the fundus in an optical path of the imaging optical system for restricting the reflection light from the focus point on the observation surface of the fundus and second beam restriction means placed in or about a conjugate position with the fundus of the examinees eye in the optical path of the imaging optical system for restricting part of scattered light to pass part of the scattered light from front and back of the focus point toward a photo-receiving element.
