PROBLEM TO BE SOLVED: To provide a device capable of acquiring an AO-OCT image and an AO-SLO image without complicating a configuration.SOLUTION: A device comprises: a first scanning part for scanning a light in a first direction on a fundus oculi； a second scanning part for scanning a light in a second direction different from the first direction； an optical system for joining an optical path to the second scanning part to an optical path from the second scanning part without via the second scanning part； a common optical system for radiating a first measurement light obtained by branching the light from a first light source to the fundus oculi through the first scanning part and the optical system, and radiating a second measurement light from a second light source to the fundus oculi through the first and second scanning parts； a first generation part for generating a tomographic image on the basis of an interference light obtained by the interference of a return light and reference light of the first measurement light from the fundus oculi through the first scanning part and the optical system by the common optical system； and a second generation part for generating a fundus oculi image on the basis of the return light of the second measurement light from the fundus oculi through the first and second scanning parts by the common optical system, in which the first generation part generates a tomographic image on a prescribed position of the fundus oculi image generated by the second generation part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】 構造が複雑化することなくＡＯ－ＯＣＴ画像とＡＯ－ＳＬＯ画像を取得できる装置を提供する。【解決手段】 眼底で光を第１方向に走査する第１走査部と、第１方向とは異なる方向の第２方向に走査する第２走査部と、第２走査部への光路を、第２走査部を介さずに第２走査部からの光路へ合流する光学系と、第１光源からの光を分岐した第１測定光を、第１走査部と光学系を介して眼底に照射し、第２光源からの第２測定光を第１及び第２走査部を介して眼底に照射する共通光学系と、共通光学系により第１走査部と光学系を介した眼底からの第１測定光の戻り光と参照光を干渉させた干渉光に基づき、断層画像を生成する第１生成部と、共通光学系により第１及び第２走査部を介した眼底からの第２測定光の戻り光に基づき、眼底画像を生成する第２生成部とを有し、第１生成部が、第２生成部で生成される眼底画像の所定の位置の断層画像を生成する。【選択図】 図１
