Zusammenfassung:To provide a scanning laser ophthalmoscope capable of preferably providing a plurality of fundus images.SOLUTION: A light reception optical system 20 of an SLO (Scanning Laser Ophthalmoscope) 1 comprises: at least three light reception elements (first to third light reception elements) 24, 26, 28; and light separation means 30 which is arranged in the optical path of the light reception optical system in such a manner that an optical path of a light extracted from a fundus oculi is branched into three paths, the first light reception element is caused to receive a light of a first wavelength region, the second light reception element to is caused to receive a light of a second wavelength region different from the first wavelength region, and the third light reception element is caused to receive a light of a third wavelength region different from the first and second wavelength regions. The SLO 1 has image formation parts 61, 62, 63 which form a first fundus oculi image based on a light reception signal from the first light reception element, form a second fundus oculi image based on a light reception signal from the second light reception element, and form a third fundus oculi based on a light reception signal from the third light reception element.SELECTED DRAWING: Figure 1 【課題】複数の眼底画像を良好に取得できる走査型レーザー検眼鏡を提供すること。【解決手段】SLO1の受光光学系20は、少なくとも3つの前記受光素子24,26,28と、眼底から取り出される光の光路を3つに分岐させ、且つ、第1の受光素子に第1波長域の光を受光させ、第2の受光素子に第1波長域とは異なる第2波長域の光を受光させ、第3の受光素子に第1波長域および第2波長域のいずれとも異なる第3波長域の光を受光させるように受光光学系の光路中に配置された光分離手段30を備える。また、SLO1は、第1の受光素子からの受光信号に基づいて第1眼底画像を形成し、前記第2の受光素子からの受光信号に基づいて第2眼底画像を形成し、第3の受光素子からの受光信号に基づいて第3眼底画像を形成する画像生成部61,62,63を備えている。【選択図】図1
