OCULAR FUNDUS IMAGING METHOD AND OCULAR FUNDUS IMAGING DEVICE

Japanese Patent JP2016198214

A

PROBLEM TO BE SOLVED: To provide an ocular fundus imaging method and an ocular fundus imaging device capable of constructing a high-quality ocular fundus image from which a ghost and unevenness in brightness are eliminated.SOLUTION: An ocular fundus imaging device includes: an ocular fundus scanning optical system 1 for irradiating irradiation spotlight of linear polarization to the ocular fundus Ef of an eye E to be examined while rotating the polarization axis, and scanning the ocular fundus Ef; an image receiving optical system 3 for receiving reflection spotlight having linear polarization in a direction orthogonal to the direction of the linear polarization of the irradiation spotlight of the reflection spotlight from the ocular fundus Ef by the irradiation spotlight; and an ocular fundus image construction unit 4 for acquiring a plurality of ocular fundus images by the reflection spotlight while rotating the polarization axis, and constructing one superimposed ocular fundus image by subjecting the plurality of ocular fundus images to superimposition processing.SELECTED DRAWING: Figure 1
