Claims (5)
第２光を被検眼において走査し、第２光の前記被検眼による反射光に基づいて前記被検眼の正面画像を得るＳＬＯ光学系と、を備える眼科撮影装置であって、
前記ＯＣＴ光学系と前記ＳＬＯ光学系とで共用される検出器であって、前記反射光と、前記合成光と、をそれぞれ受光し、前記正面画像および前記断層画像を形成するための受光信号を、それぞれ出力する検出器と、を有する眼科撮影装置。 OCT which scans the measurement light from the first light source in the eye to be examined and obtains a tomographic image of the eye based on the combined light obtained by combining the return light of the measurement light from the eye to be examined and the reference light Optical system,
An ophthalmologic photographing apparatus comprising: an SLO optical system that scans second light on the eye to be examined and obtains a front image of the eye to be examined based on reflected light of the second light by the eye to be examined;
A detector shared by the OCT optical system and the SLO optical system, which receives the reflected light and the combined light, respectively, and receives light reception signals for forming the front image and the tomographic image. , An ophthalmologic photographing apparatus having a detector for outputting each.
前記ＳＬＯ光学系は、有害光を除去する有害光除去部を有すると共に、前記有害光除去部を通過した前記反射光を前記検出器に導き、
前記有害光除去部を通過する前記戻り光、および、前記光結合部を通過した前記反射光、のそれぞれが前記検出器に導かれることを妨げる光学素子を有する請求項１記載の眼科撮影装置。 The OCT optical system includes an optical coupling unit that synthesizes the return light and the reference light, and guides the synthesized light obtained by the optical coupling unit to the detector.
The SLO optical system has a harmful light removing unit that removes harmful light, and guides the reflected light that has passed through the harmful light removing unit to the detector.
The ophthalmologic photographing apparatus according to claim 1, further comprising an optical element that prevents each of the return light that has passed through the harmful light removal unit and the reflected light that has passed through the optical coupling unit from being guided to the detector.
前記光切換手段による切換制御に伴って逐次取得される前記断層画像と前記正面画像とをモニタの同一画面に動画画像として並べて表示する表示制御手段と、を備えることを特徴とする請求項１から３のいずれかに記載の眼科撮影装置。 Light switching means for switching light that scans in the eye to be examined substantially alternately between the measurement light and the second light;
The display control means for displaying the tomographic image and the front image sequentially acquired in accordance with the switching control by the light switching means side by side as a moving image on the same screen of a monitor. 4. The ophthalmologic photographing apparatus according to any one of 3 .
