PROBLEM TO BE SOLVED: To provide a scanning type ophthalmographic apparatus capable of constructing a high-resolution frame image by removing aberration caused by a deflection angle of a mirror.SOLUTION: A scanning type ophthalmographic apparatus includes: an fundus oculi scanning optical system 1 that scans the fundus oculi Ef, while applying illumination spotlight Sp to the fundus oculi Ef of a subjects eye E an image receiving optical system 3 that receives the illumination spotlight Sp and outputs an image receiving signal and a fundus oculi image construction part 4 that constructs a fundus oculi image Ef using the image receiving signal from the image receiving optical system 3. The fundus oculi scanning optical system 1 has a scanning mirror 10 for scanning the fundus oculi Ef in the vertical direction and the horizontal direction, and the scanning mirror 10 is reciprocatingly oscillated between a forward movement direction and a backward movement direction by a mirror drive circuit 30. A mask 42 for adjusting a generation interval of a pixel clock PL is provided at a position offset from an optical path of the fundus oculi scanning optical system 1 and a position on a plane conjugate to the fundus oculi Ef. The fundus oculi image construction part 4 adjusts an image importing interval with respect to a deflection angle of the scanning mirror 10 using the image of the mask 42.COPYRIGHT: (C)2013,JPO&INPIT【課題】ミラーの振れ角度に起因する収差を除去して高解像度のフレーム画像を構築することが可能な走査型眼底撮像装置を提供することを目的とする。【解決手段】本発明の走査型眼底撮像装置は、被検眼Eの眼底Efに照射スポット光Spを照射しつつ眼底Efを走査する眼底走査光学系1と、照射スポット光Spを受像して受像信号を出力する受像光学系3と、受像光学系3からの受像信号を用いて眼底像Ef’を構築する眼底像構築部4とを有し、眼底走査光学系1は眼底Efを垂直方向と水平方向とに走査する走査ミラー10を有し、走査ミラー10はミラー駆動回路30により往動方向と復動方向との間で往復振動され、眼底走査光学系1の光路からオフセットされた位置で眼底Efと共役な面の位置に、ピクセルクロックPLの発生間隔を調整するマスク42が設けられ、眼底像構築部4は、マスク42の像を用いて走査ミラー10の振れ角度に対する画像の取り込み間隔を調整する。【選択図】図1
